If you've been roleplaying awhile, you have an example journal. The idea is, you post here to get people to check it out. This can help you get certain storylines filled, whether they are private or for a community. It will also introduce you to an array of new and talented writers that you might otherwise not come into contact with.
Do not ask for homes! There are places such as rpads, rps and pbads for that. Your journal must be an example journal in some way/shape/form, or at the very least have a list of rules/people you play/etcetera. Don't attack anyone for what they keep in their journals: if you do not like it, don't play with them, simple as that.
