Signatures

I don't understand why Adobe is being so difficult with this. So I got a document that had a signature. I needed that signature on a different document so I'm trying to figure out how to take that signature and move it to the document I need it on. Is Adobe forcing me to pay $15/month to do this? I'm also limited on how many signature request emails I can send. Is Adobe also forcing me to pay more money? I only have to send about 6 request emails but I don't want to wait 60 days to do that and I certainly don't want to lose $15 just to get a few signatures. Is anyone else facing these problems? It seems like everything that I need to do requires Adobe Acrobat Pro but yet again that could just be me being a cheapskate.
