No, derivative works do not allow you to bypass copyright. The original code still belongs to the authors who wrote it. So even if you wrote say 80%, that 20% would still belong to the respective owners and you would need permission to sell it.
it's been pretty much recoded... i re did pretty much everything on it..
I think everyone is understanding it quite well; you recoded it, but not for 100% which means you do not own 100% of the code, which simply means you can not sell or put it up for public download without consent of the original author(s).
What you CAN do; is sell your product as a Add-on to the original code; which means the user need to purchase the original software and then use your add-on software.
In any case you are here at the wrong place to ask; you should contact the original authors.
I don't even see why you made this thread if you refuse to acknowledge the facts.
Rofl i know the facts, you guys ovbliviously dont know nothing
If i used ipb 1.3 (FREE FORUM SOFTWARE)
And i REWROTE IT. meaning I REWROTE THE CODE.. i shouldnt even made this topic, just shows how stupid you guys are, saying this.
If i rewrote the code it's obliviously my code i could do wat the heck i want to do with it. It has no ipb 1.3 code in there and im sure there's no law saying i cant look @ coding and learn from it and right my own right? LOL
