Hear ye, hear ye!
Mark Jacobs popped over to the F13.com forums to explain exactly why they're shutting down the beta servers for two months.
It's really simple. We got lots and lots of data (some great, some good, some not so good) and we are going to act on what we got. That's one reason we started beta as early as we did so we could gather that data now, not later, when we have a chance to fix/change/improve things. As an FYI, the tools we are using now I would have killed for with DAoC, if we had then what we have now, a lot of dumb stuff would not have happened.
For an itemized list of what they are and aren't doing, head over to the F13 forum post.
