      Ummmmm – you can’t do that. PHPBB is GPL; if you’re forking it, you have no choice but to remain GPL.

    Thank you so much for this. We are developing free, use-as-you-want a whole “Service Operating System” platform that is complete open source. It uses technical self-automation modularity-structure that requires open source distibution.

    While I see in the future that I might have to comment on the chosen wording of the license (for one particular four-letter word), the expression that it stands for “not-so-free-software” is required in the current license hell.

    I am happy to state that you just saved me half a day for putting the WTFPL up!

    DebianWomen Statistics has a graph of the number of female participants in the Debian GNU/Linux project. The code for the graph is linked at the bottom and is under the WTFPL.

    [By the way, I love your front page picture. It took me several glances before I realized that that third guy was doing what the fuck he wanted to!]
