There are countless places on LiveJournal to display, discuss, and discover user icons.
This is not one of those.
However, this is a place to list those, pimp those, link to those, and generate publicity for those.
The idea behind this community is, if you've created, joined, or watch an icon community that you want more people to know about, make a post about it here and let the publicity roll in! Alternatively, if you're looking for a kind of icon community and haven't found it, feel free to ask here!
The rules are simple:
1.) Keep it to the point. 2.) Don't be rude to other people. 3.) No spamming. It's not a strict one-listing-per-week kind of place, but there can be too much of a good thing. 4.) You are allowed to promote your personal icon journal or community, but remember, no-one likes a braggart.
