Cheers for the heads up. Saturday night isn't too bad timing I suppose, most of us are probably out or watching telly rather than hunting through forum threads at that hour.
Quick question though - will there be any notice posted if it runs over and bleeds into Sunday morning? I've had it before with other sites where "a few hours" turned into most of the next day and you're left wondering if somethings actually gone wrong or if they're still working on it.
Also, any chance this maintenance includes fixing the image upload issue a few of us have flagged? Would be nice to finally get some photos up properly in teh haunted objects thread without it timing out.
