Yes, I do have a problem with that considering that the only thing you gain by publishing elsewhere is more control on user input (admin stuff, generally).
Secondly, I honestly believe that a move like this will alienate a large percentage of your userbase. I know that I won't be the only one who doesn't like the idea of signing up to third party forums for specific information that could be just as readily available here.
If you wanted user control - which I have seen you talk about - then fine, just don't make the downloads for registered users only and then everyone is happy.
Don't get me wrong, I appreciate all the work you've done - past and present, but I honestly can't justify jumping through hoops to use the code.
