I type, I post, get a blank page, refresh, get a "you're not allowed here" error, then post shows twice at least.

I, too, only get a white page after "make post". Still. By now, after a heartattack each time, because I'd wasted half an hour composing my topic, I go back to the main page and so far, thank goodness, always have found it there.

Yep, exactly the same, learned it the hard way :D We souldn't have to tho...
