Sorry about that folks. There is a form in place now which works (but has an even smaller submission limit) and I'm going home to where I can use JEdit and code my own one that won't have any stupid limits. That'll teach me to take the easy way out!
Nominations are still open and will remain so for around another 24 hours. (I initally said midnight on the 29th, but I won't be online until the library opens at 10am so it'll be then.)
BUGGER! Just thought I should also check the WKA form and it's got the same problem. Ok then, I'll be back in a couple of hours with new forms and a decision about extending the WKA.
