WELCOME to ghetto_fobulous. A community that's all about fun and our ghetto alter-egos!! Hence those who are already part of the Ghetto Fobulous FamLay have nicknames such as Naynay, Shaniqua, Tanisha, Tariq, Latoya & Keisha. You are open to post whatever you like, but be aware that the community is being moderated. If any posts or comments are offensive to anyone, they will be removed from the community.
1) Probably the easiest thing to do is to download the latest client for your platform that supports the feature to post in a community. You can download a client here -> http://www.livejournal.com/download/.
2) Clients vary on how to post. On the LJ client, you can post on another community that you have joined by clicking on the Livejournal menu tab. From there, go to Select Active Journal. You can then click on the journal you want to post in.
On Semagic, the Active Journal option is featured by clicking on the scroll tab under the box where you type all your entry text in.
