We'll be doing a little much overdue maintenance on the forum this weekend and there will definitely be a little downtime. (more like "weirdtime" mixed with downtime).).
While you see the message above, the work continues. From Friday 2/27 until it's gone, post messages at your own risk.
In the case of catastrophe it could be 1-2 days.
There will be some minor changes to functionality and design when all is said and done. Just updating it but it's been a long time and may not go smoothly.
