hello bglynn,
Enter the control panel -- select application form settings, set the options appropriately and click submit. vars_appform.cgi will be installed automatically.
Currently, im not sure if this version is compatable with sticky threads v1.6. I know Jordo changed around the sticky thread hack -- and i haven't had time to examine the differences. It will be about 4 days before i gain enough time to check out sticky threads 1.6 and perform adjustments to the application forms hack in order to make the two hacks compatable.
