At the moment there are some problems that cannot be solved within the current set up without privs one of cc's newest clans is freemium forces. All its members are freemium so if they want an in clan tournie they will need to set up public games that anyone can join.
The above problem also applies in clan challenges where both players are freemium.
Yes someone else could create the game then drop it but if your challenge involved 1 v 1 games this becomes impossible.
As any earlier post indicated if this site wants to support usergroups it needs to do something about this between now and when rivals comes out
Rivals will be hopefully a big help (see links below) but surely something can be done in the meantime as we actually have no guarentee that rivals will even be rolled out with the forums update and likewise we have no idea as to when this will happen.
rivals details from first version to newest release
phpBB3 Gold aka phpBB 3.0 was released worldwide on December 13 last (people will have probably seen it on other sites.
It has been indicated in the past these two will be rolled out on here. However at no stage has it been indicated these will be rolled out together (although im hoping this is the case)
This thread/debate becomes academic if this roll out is imminent but if it is not then the current rules need to be changed until it is.
