Weird license question.

[Cap'n Steve]

Ok, I already bought vbulletin, but I didn't know where else to ask this. What I'd like to do is develop a hack for integrating Perl programs with vbulletin. I need to know if I'm allowed to basically copy some source routines into a Perl module then modify them to be Perl compatible and release it on www.vbulletin.org. I'd be willing to start from scratch, but it would be nice to be able to keep it as similar to the vbulletin source as possible.

you have 100% the rights to develop hacks based on the code you find in vBulletin... (or how would anyother do ??)... 100% of the hacks released at vB.org are based on the source code, so it's natural that you can do it...

the restriction occurs when you want to create a independant tool based on the source of vB... this would not be possible... but as a hack, extension, module, whatever,... it's ok!

The only restriction im aware of is you are not allowed to post the entire source code of vBulletin and/or post an entire file contained within vBulletin. In other words I can't release a modified copy of a vBulletin file.

Say I made a modification to showthread.php. If I want to share this with others I have to document the changes, I'm not allowed to pass around my modified showthread.php file.

So, seeing as you don't seem to be doing anything like that I asume what you want to do is ok, you might want to wait on a dev or support member to verify that before releasing to the public tho.

You should check at vbulletin.org since they have specific guidelines on releasing hacks there.
