Thats something this site should think about as it grows even bigger. Having more MODS or something who can shut down threads and combine threads or something. We get quite a few redundant threads here (under different names).
Thats not a simple issue. You gotta balance alot of things,so it doenst turn off people also. Something to maybe think and discuss among the admin.
Thats one of the reasons we created the UFC Smacktalk forum. It should keep some of the "shouting matches" to a minimum, and also move all the "cheering" and "name calling" to one area... will keep the site more pure for MMA fans.
