A heightmaping tutorial would be very useful. I also think a sample design document is a must, since this essential step is often overlooked by mods and would save everyone a lot of work down the line. I can try and put one together during the week, though I don't know when it will be done (finals, and all that). Besides that, a list of available and needed modder's resources that can benefit the community at large. Anything else not project specific that we'd like to see at launch?
Unique ID's for projects are indeed a must. Every team I've worked with had them by default, so I didn't even think of not having them

Listing them on the wiki to make sure they don't overlap is likewise a good idea.
Is everyone fine with Beyond Skyrim (beyondskyrim.daryam.com) as the name of the wiki/forum/support group?
Anyone have any preferences for wiki software? Right now I'm thinking MediaWiki, which is used to run all the wikipedia sites and uesp, among many others.
