Updated forums

Hey, miners! I've added a couple forums and sub-forums related to mining and tweaked a couple under the category of PROHASHING. The orange Forums rules boxes at the top of each individual forum now pertain to that specific forum and link to the overall Forums rules on the PROHASHING site, so please make sure you're checking these out before you post.

I'm still in the process of going through and assessing what, if any, new forums may be needed, so if you have suggestions, please feel free to reply to this thread.
