Thanks to everyone for a lively start to the first week. 21K students have been active in the course so far. This is the first time the course is being taught online, and we appreciate your participation and helpful feedback as we iron out some kinks. We are grateful to those of you who fearlessly watched lectures and submitted assignments on the very first day, and are especially grateful to those who are helping others through the forums.
Guided by the forum discussions, we have compiled some troubleshooting info for NetLogo and Gephi. We encourage you to help make the wiki our go-to spot for useful info by contributing to it. Don't fret about Gephi and NetLogo. If you can get Pajek, UCINet, or similar to work, you will be able to do "Gephi" assignments. The forum and wiki would be great places to help one another translate between these different software packages. NetLogo runs very reliably as a standalone application, so there's no worry about being able to run/use NetLogo. NetLogo's creators have also given us updated browser applet software, so e.g. the community visualization demo should be usable with more browser setups (as long as you enable Java!).
Here are some of the most common issues: 1) Video playback is flaky: make sure you are using the most up-to-date browser. If all else fails, download the video. 2) Can't open pptx slides: under 'video lectures' we have now made PDF versions available. 3) NetLogo app won't load, Gephi won't install (see above) 4) Where is dining.gephi, HW1 template 5) formatting HW1 for auto-grader (use Notepad++ or similar on Windows to keep the text clean, upload the .gml from GetNet directly, also see forum for additional tips) 6) HTML toggle obscures video in Lecture 1A (we have removed the toggle)
What you can do to help: * keep reporting issues in the forums * search the forum before you post (is there already a thread with your question?) to reduce clutter * vote up interesting questions and helpful answers, mark questions as resolved if they are * share solutions to frustrations you've encountered * add information to the wiki
Reminders: * HW1 is due next Friday Oct. 5th * Twitter: @SNAcourse, #SNAc, thanks for all the thanks, enthusiasm and interesting thoughts tweeted to these! We've been admonished about retweeting too much, but we do appreciate them. BTW, if you'd like a response to a request for help, the forum is a more reliable/helpful place. * Did we mention how we'd like to build up the wiki? Those useful tools you were mentioning in the forum, let's put them in the wiki. You plan to do assignments in Pajek? Share Pajek functionality on the wiki. You're writing lecture notes? Please post them!
Lastly, it's amazing to see different communities come together around shared interests. Hope that continues.

Assignment 1 ready to view, but not ready to submit
From the forums I see that many of you just can't wait to get started on the first assignment. It is now posted here, but we're still working on getting the 'submit' button to work properly on the live site. So please feel free to get started, but don't expect flawless grading until a day or two from now (don't worry, you can resubmit as many times as you like and the highest score will be counted).
Also, some of you have been tweeting about using the netvizz app to pull your Facebook networks. I have been in contact with the creator of the netvizz app about the anticipated load on his university's server, and he very graciously allowed me to use his code on Coursera's servers. So please, use http://snacourse.com/getnet/ to download your network instead of netvizz. Things might still get overloaded, but they'll get overloaded on our servers :). As an added bonus GetNet directly generates a GML file which is what you need to upload as part of the assignment.
Finally, Rodger Devine, a member of our fearless teaching staff, has put together survey results from our pre-course survey. Have a look.

SNA course starts today
We're just about ready to get started. Week 1's lectures are available (apologies for the mediocre sound quality on a few of the clips, it gets better in subsequent weeks...). Assignment 1 will be available by Tuesday Sept. 25th and will be due on Friday, Oct. 5th.
If you have questions, please check out the FAQ. If they are not answered there, please post them to the forum. We also have a course wiki, that has additional information and that you should feel free to contribute to. My assistants (Rodger Devine, Bonnie Yu, and Ke Wu) and I will be checking in on the forum and wiki and helping out.
I will occasionally be tweeting about the course as @snacourse, and the hashtag we have settled on for now is #SNAc.
I'm thrilled that so many of you have decided to give this course a try. Social (and other) networks everywhere, prepare to be analyzed!
