Thanks for the offer Kilsek!
But I would prefer if we could continue this thread via PM, because I don't want to bore the others with this kind of technical discussions. I hope you are OK with that.
Just to quickly answer your questions:
1) I want the subforums to remain visible straight away when the page gets loaded.
2) I tried using the index and played around with it a little bit when the forum started, but in the end I decided not to use an index page. I want the forum to be accessible straight away when you open it.
3) I did the "thing with the warbands" by customising the RPG function in the module section of the administrator panel a little bit. I'll send you a PM with details.
I am closing this thread now. Feel free to send me a PM if you would like to keep discussing any other "admin stuff".
