Because everyone was making signature tutorials and I couldn't keep stickying everything, I've made a directory thread which just links to everything. I'll update this thread when new tutorials are posted.

Just a brief note, members please keep your signature under 200 PX otherwise you will get that signature message. Please note that this includes both text and images, so you will still get the message if you have crazy amounts of text in your sig. The other moderators and I WILL be removing parts from signatures if you don't fix them. So if you want to choose what stays and what goes, do it yourself before we do...
