We know you have an opinion on how things should be run around here. These are suggestions for the forums, and the website.This forum is not a place to ask for suggestions to your own coding (or otherwise) problems.
If you post (quick-reply) in Digitalpoint Forums, you'll find that the page doesnt reload - instead the post is just added to the thread without refreshing - using AJAX I guess. I think that's a really cool feature and have found this only in that forum. I dont think its part of vbulletin - must have been added by someone else.
I think thats a really good idea and should be implemented in other forums too.
There are complications about using AJAX as with any new technology. Consider the end post of a page. Most people work top to bottom. They go off looking at a topic in a tab and the next thing they know the "index" page has changed. Good design and user awareness is essential.
