When there is clearly a new post, clicking on "View New Posts" gets "Hmm, we can't reach this page." (not a real problem)
When attempting a search, the results are "Sorry but you cannot use search at this time. Please try again in a few minutes." (3rd party search engines work better, anyway)
When clicking on "Send a personal message" (as to Mr B about the above) the results are "Hmm, we can't reach this page." (he's probably too busy to talk to me, anyway ;-0 )
