If I may ever so gently make a comment. I think what he is trying to accomplish is (for free or paid) "styles/themes" site. This does not make the forum (or PunRes) paid, nor would it require anyone to even go for it. It would simply be something that people may want, and could pay a couple bucks for it rather than doing themselves.....
When I released phpcoin, it was rather plain (much for the same reasons as punbb), but a lot of people simply wanted a different look. Many people installing software have NO idea how to change it. One person started free / paid themes and to my amazement, that was the difference for some people and they scarfed it up....Did I get pissed that someone made money from my project- yes sort of, but they're not really getting paid for your work, but instead for additions to it....
To this day, phpcoin is more popular because of it. (and in some cases- more popular does mean more donations )
Just imho...
Every Day Above Ground Is A Good One!!
