Well..
I feel TibWeb has always been plagued by problems from it's conception onwards. Mod creators always had to pick one forum to focus on, TibWeb or PPM. And because of certain things in the past (Felix fucking us over with TumSun so we had to create TibWeb, downtimes, forum troubles, but perhaps more importantly lack of interest from our admin team and a lack of staff) things just got worse and worse really. I've made it clear on multiple occasions that if anyone is enthousiastic enough they can take over TibWeb, but perhaps I should have simply made a news topic about it to draw more attention. The offer still stands really. I'd still pay for the hosting and the IPB License (well, mostly). I just don't have the time nor the interest to really work on this site anymore. I don't play the newer CnC games as I think they're crap compared to the old ones, and my interest in TS is all but zero.
That said I'm all for a mapping competition. I just don't want to organise it myself
I'd help ofcourse by setting up the necessary forums. There's a decent chance I might be able to acquire some pretty nice prizes. (I actually won them myself recently but didnt receive them yet, they're very CnC / Kane related.)
The competition would need to be fairly well advertized though as we'll need to attract many mappers from other sites aswell in order to have a decent amount of people competing. I'm sure PPM would help us out by posting updates in their news section. I don't visit any other sites myself, so I don't have any more suggestions
