formparse patch
Date: Fri, 10 Aug 2001 15:42:50 -0400
I ran into a problem with your formparse code, it truncates POSTS over
4k Anyway I made a quick-n-dirty patch.
I'll use your cool new form thingy I saw on the list archives when it
comes out. Any estimates for how long I'll have to wait?
I'm not on the list BTW so please CC me any replies.
