Is it possible to have vga video file on my forum (to-hawaii.com/forums)? and if so how can I do that? also is a Skype entry an option on membership profiles?
Not sure what you mean on the first one to be honest. But the second is a big yes.
You can either use this:
http://mods.mybb.com/view/skype-mybb
Or just create a custom profile field, and force it on registration.
Regarding my first question, I need to add .VGA video on my site. how can I do that?
How to you mean "Add" Does each user have their own stream? Is there an available API? It could be as simple as an extra page to a mycode or a plugin.
