You still might not be able to use signature and avatars as long as you are a newbie. You also cannot post image as long as you are still a newbie, the time limit between posts, the time limit between reports post to mod, and PM limit. But good, being whitelisted means you've relieved some of the restrictions but not all of them.

Also you are in luck because one of our global mods answered your question.
OP now start your fun journey, forget the things that were less fun before because I hope there are many valuable lessons that you have learned during your reading even if you don't post.
