Hello friends, I have 4images gallery (http://www.4homepages.de/) installed on my site Musiclocha.com And i want to add a vanilla based forum to my site. So, i am looking for some bridge between these two softwares. Like user has to just register once and user can use same login info on 4images gallery and on Vanilla forum! --------------------------- I am also looking for some addon which can hide links from the posts! Like user has to say thanks or reply to a thread to see the live links? Anybody have a addons for/like these?? Many thanks for your help :)
