This has been discussed many a time. Believe it or not, the Mod team hates these forums more than the players do.
The way that these forums work, it,s not simple to assign powers directly to leader. Also, when deleting threads, it causes major lag on that persons computer. I usually take a list of what I need to clean, then delete them and go to sleep. Hopefully it's done by the time I wake up the next day.
We have discussed using a new forum, but with the amount of time required to transfer everything, setup new forums, and make sure it's everything we want/need, the time spent outweighed the sucktastic forums we have now.

Arby: A very strict mod, reminds me of a fat redneck who drives a truck around all day with a beer in one hand. I hated this guy at the start, however, I played a round in PW with him where he went as an anonymous player. Our fam got smashed up and everyone pretty much left. Arby stayed around and helped out the remaining family. At the end of the round he revealed himself.... My views on him have changed since. Your a good guy.....
