Ive been reading over GPL licences and im still a bit confused. Actully I never really looked into it until a few nights ago.
Ive written a quite a few modules for my company for GPL licensed software that we use in house, mostly for oscommerce. Ive been thinking about offering a few up as contribs for free, but there are a few that I spent allot of time on and would like to sell.
From what I gather, I can charge for downloading the software, but once someone downloads a copy, they can make a few minor changes, and then sell the code, or offer the code for free. Is this correct? Can I copyright my contributions so at least I get credit, is there anyway that I can maintain a licence on the software so that it cannot be redistributed without my permission?
Can someone give me the inside scoop please? also usually put headers in my code like
// designed by (my name) (date released) (version) //
but was also wondering if theres anywhere I can get good examples of copyright disclaimers/ or template licence agreements for my code.
Thanks so much for your time guys. I really do appreciate it.
