yes it can but theres a problem if you edit your post it will re-do the changes. you need to make it make a unique change that it will check for on edits.

I dont know how plugins work in vb yet.
If i will find out i will do it :P

does tis mod wk fine frens ?

it is not possible to do as plugin - as plugin hook is before checking if html is allowed.
if you have html disabled in posts it will change html youtube code to normal text.

i added request for hook - if they will add it in next version then ill make plugin for it.

Great mod worked fine on my 3.6.4

...nevermind.. lol

works great on vBulletin 3.7.2... only thing is when people go to edit their posts, it does not show the link anymore. Other than that, everything works perfect!!
