Mudcat is not unusable at all. It is easily usable if you sign up with a legitimate email address. I don't understand what your problem is. You evidently found the thread easily enough to be able to leave a post on it.
As to prehistoric, that is a bit exaggerative. What Mudcat is, is....... traditional. It has not yet formally undergone the folk process. I quite like its current format.
Sorry for the aside, but last post was a bit.... off-putting.
I understand that Kev is now all sorted re stewarding. I am looking forward to meeting a whole new group of mud catters there.
