For me there is no problem in asking support for everything... I also deserve the right for supporting what I want to support.

You get no argument from me there as we all like to help.
I would even install phpBB3 on XAMPP to help these phpBB3-lovers where I could - But I draw the line at installing and helping them with MODS or anything else that is not provided by you.
I know it's difficult for some people to come to grips with, and understand what they have installed and / or how to go about learning what they have installed, or what to do when problems exist.
But the fact of the matter is, some people seem to think that this is a base for expanding their phpBB3 knowledge, and you're not always around the place to cover that.
Neither are the any other phpBB3 users regular enough here to provide timely help.
As I said, we all like to help, but us uneducated helpers with lack of knowledge about phpBB3 MODS and whatever may be better off staying out of here.
