Just a quick note of appology in case you've tried to add a comment to Tim's Blog in the last 48 hours and come up against error messages. Comments should now be fully working again.
The server hosting Tim's Blog fell foul of a number of systems trying to post comment-spam all over the place which a) brought the server to a grinding halt, and b) caused me to try and up the defences, messing thinks up so no comments at all could be posted.
I've since un-messed-it-up, and am looking at other ways to keep the spam at bay.
