branchandroot (who has been wonderful so far) and I working on an official list of tags so it will be easier to search for something you need help with, since chances are, someone else has already asked about it and it's been solved/explained.
If not, feel free to make a new post and ask. The more information you include in your post, the easier it will be for someone to help you. If you have a custom theme layer or custom CSS, please include it under an LJ-cut, or provide the url.
I'm really glad to see that there is already a bunch of great stuff on this community, guides and stylesheets submitted by you guys. I'm amazed at how much some of you have already figured out on your own! Thanks for sharing, and please continue to :D
For those of you who are still totally confused, I plan on making visuals that explain how the layout is structured (think "Expressive for Dummies"), and eventually a comprehensive CSS guide like s2flexisquares has.
If anyone is interested in helping maintain this community, either leave a comment or send me an email (firstname.lastname@example.org). We're just starting out, and any help is appreciated. (note to self: create a list of tasks)
