Adding new Action to give Thread Creation Permission

Hey guys i have a Sig Shop as a Sub forum to my Graphics Forum (A forum where people can purchase customized sigs for a set price in uPoints.)

I want to make it so when someone purchases a "Store Front Holder Deed" from the uStore it gives them acess to create a new thread in that forum and set up their store (nobody else will have acces to do so), Can somebody help me and tell me how i should go about doing this? I already know i'd probably have to make a new .php file to do this but can someone tell me what to put? Thanks yall!


I'm using .95c
and 3.0.7 VB
