Did you know you can sell your signature in forums? I just read about it so I don't know much about it. I came across Sig-Link and apparently you can check how much your signature is worth by putting in your total posts and your average posts per day. Some people have sold their signature for about $100 a month. Of course these people probably have over 5000 posts.
If anyone have any feedback on this, please leave a comment. I learned about this from reading in the Digital Point Forum
