We seem to have a couple of faults, which have been cropping up with increasing frequency over the past few days.
Some comments have been mistakenly caught by our spam filters. And the system has taken a sudden dislike to things like pound signs and umlauts.
We are trying to sort out the problem. In the short term, please try using the plainest text you can.
And sincerest apologies for the frustrating inconvenience this must have been.
