If I upload some videos to my forum is there any way I enable them like youtube videos??
Do you mean via the BBcode? You could just upload your video to YouTube and make it private so only those with the URL (at your forum) viewing would see it.
Anybody know how to do this??
You should really consider using YouTube, Vimeo, or some other service like this. Hosting your own video and player is a serious pain.
If you want to continue, I can't help, sorry.
