Well, this is a strange one.
Sign Profit dissapeared a while ago now, and before it did it paid me about $60 or so.
It had gone and was long buried, but it is now back - new owners, and paying.
It paidf me everything that I have been owed, and has paid me a few times since.
SP is a programme that pays per unique view of its banner in your signature. You can only show this banner in approved forums.
It is currently paying $1.55 per 1000 views, to pecunix OR Liberty Reserve.
Have a look - it costs you nothing to join, so you have nothing to lose:
