I wondered why they went with the built in website forum software, versus a very popular/flexible forum software, such as PHPBB, MyBB, ProBoards, etc?  They are easy to integrate, and very proven, common, familiar, comfortable and widely accepted.

I was just surprised what they have for forums.  The edit screen is a little "basic", the sorting is awful (but I hope thats fixable) and they lost some options on search that used to be helpful.

(also surprised they changed the name of the old forums to forumarchive, versus just making the new forums something like forum2...now every Google link to all those years of content is wrong)
