General SMAUG building resources

I was wondering if anyone could point me in the direction of some good building resources (building rooms, mobs, items, etc). I started co-building a MUD four years ago, but due to personal issues had to stop. I'm wanting to get back into it but I'm having a hard time tracking down good information. I've pretty much forgotten what I learned back then and I can't find any of the resources I used by then. Wish I had saved those bookmarks...

I did a list of SMAUG commands a while ago, if that helps:

Thanks for the reply Nick, that will give me nice starting point.

Also I was able to figure out where Hernes's Building Guide has moved to since it is no longer at the address that is linked all through the various SMAUG related forums.

Everyone may have already figured that out, but just wanted to get the information out there if it wasn't already.
