I'm just going to make an answer to all the people who have been wondering how to post their signatures and avatars..
Okay for the avatar.
Go into my controls - edit avatar - if it is on your computer click browse, find the file and choose it. Click Update Avatar. That's it.
Remember Avatars can be 120x150 pixels.
Okay for the Signature.
First you'll need a website to host the image. This is a good one.
http://imageshack.us/Register there and host your image. Then check My Images. Find the line that has the letters IMG around the text inside. Copy that and then come back to SEF. Go into My Controls, Update Signature and click the IMG code button and paste the code from imageshack.us. Click update Signature and that's it.
Remember Signatures can be 500 x 250 pixels.
I hope I have helped and if I have not PM me.
