No worries at all, good to know in advance rather than just finding the site dead at 11pm and wondering if somethings gone wrong lol. I've been caught out like that before on other forums, spent a good half hour thinking my internet had packed in.
Saturday night works well for me actually, I tend to be out then anyway. Hopefully the maintenance sorts out some of the image upload issues I've been having, attachments have been a bit temperamental lately when I try to post photos from my investigations.
Anyone else here who does regular late night browsing just keep an eye on the clock Saturday. Worth saving any drafts you're working on before the window hits.
