The reason I'm suggesting another discussion forum is that websites use many different internet technologies. And there is no specific place to discuss a combined technologies for a website in pre-production or post-production.
Like you said, I could post in the forum of the technology I'm using but say for instance I'm trying to figure out methods for doing something then it becomes a mess. When an
HTML topic becomes a
php topic to javascript topic. I'm not a huge poster. More of a reader and I just think any of those additional forums would help organize the site and attract more members.
