cool smile thanks for the quick replys.

The only thing is, your friend have the ability/freedom to read, edit, and distribute your PunBB setup and PunBB by itself.

You mean I need to supply him with the source, and he'll be allowed to modify/redistribute it according to the GPL? I've got no problem with that, can't picture that he'd even know there was such a thing as code that ran his site though big_smile

hi, I've read the faq on licensing and I'm still a little unclear as to what the GPL allows me to do.
Basically I'm designing a commercial site for a friend, it needs a forum with logins integrated with with main site. Rather than reinventing the wheel I'm looking at integrating some of the various forum packages out there into my code for the main site.  Possibly I might expand this to include using for comments on articles etc later. I'm still at the planning stages.

Obviously I would need to at least include() punBB files in my code and quite possibly modify the punBB files. So, my question is if I'm paid to do this does this count as distributing modified/derivative code? Therefore against the GPL? It would only be used on this site, not made available or sold elsewhere. I could integrate with a commercial package like vbulletin of course, but I thought the code for punBB looked a lot less bloated and would be less hassle to mess around in.
Any advice gratefully appreciated.
