Ahh thanks, I had written a script to filter out any swearwords I typed a while back, which also had the effect of evaluating things...
It's pretty neat so I've changed it to an input evaluator, this is it for anyone who is interested;
on *:INPUT:#: { if (/* !iswm $1) { var %replace = $1- | msg $active %replace | halt } }
Now if someone asks me a simple sum I can just type it in and i'll look smart with the answer!
Thanks again
