Just simple things that when I figure out how to do things that I think others might want to do, I'll post it here and such.
How to Add a Signature:
1. Go to Profile > Signature > Create Signature in the box
2. Go to Profile > Preferences > Check "Always Attach Signature"
Other than that, you'll have to manually attach your signature when you post by expanding the "option" bar under the send button and selecting it.
