Fair enough, these things need doing. Saturday night's not ideal timing for me personally as I usually do my weekly re-read of the Paulides missing persons cases with a brew but I can work around it.
One thing I'd ask the admins - could you give us a rough window for how long it's likely to be down? Even just "a few hours" or "most of the night" would help. I've been on forums before where maintenance ran way longer than expected and people were left in the dark (no pun intended given what we discuss on here).
Also worth flagging for newer members - make sure you save anything you're mid-way through writing before Saturday. Lost a fairly detailed post about a Men in Black sighting once during an unexpected outage and never quite managed to reconstruct it the same way. Learned my lesson after that.
