Sorry to pop your bubble but some of the "free samples" that you have do not meet the file size requirements for a signature. I'm not saying that every single one you make will be that large, but I can assure you that if you make most of them like those "free samples", they will be taken out of the signature and be replaced for a message nobody wants to see.
Also, nice sigs anyways...
P.S. I forgot what the requirements are but I'm sure none can pass 180kb x.x Forgive me for typing so... mean XD
