I've been looking around on the MCWB website and I've thought of things that could make the site much easier to use.
Finding Friends on the site can be annoying especially when there is no clear link to the friend search. I only recently found the link to finding friends. My friend SlyGamer agrees with me on this one. So one suggestion is to make a clear link to find friends.
Another thing noticed is that on forum post you have the name of the person who has posted. Some of them do ask for a pm maybe for video links, what mods would be good to use etc. So another suggestion is that you can make the names actually become a link the their profiles.
And the last thing is that searching for Forum posts is hard. You have to go through the whole page if you want to get to a post for example, if I was to go in to the "mod" part of the forums and try to find a forum post that now isn't on the front page I would have no hope of finding it easily. So the last suggestion is to put a 'simple' forum search bar for people who need it.

Thank You
