These are some options for getting help with StatusNet software, especially with installing and configuring it.
Read the fine manual
OK, well, not really a manual: more like a README. The tarball includes a README with a ton of information.
Read the fine source
Another great "source" of information (*kneeslap*) is the source code. Yes, it's hard to understand if you're not a techie.
The StatusNet mailing list http://lists.status.net/mailman/listinfo/statusnet-dev has lots of interesting people who can help out.
The #statusnet IRC channel on freenode.net includes a lot of friendly folks, not least the StatusNet core developers.
