Can't see any problems with a single post here or in off topic mentioning the fact that you have added a new script to the store but the forums are not really the place for advertising your wares, that's what the store is for!
*** Edited to add: If you look at the forum descriptions the "3rd Party Models/Media Chat" one mentions having media to sell so maybe that's the place to post
Been there, done that, got all the T-Shirts!
