I am running Wakaba 3.0.5 and i want my users to be able to post embeded videos and swf files. Example: a flash video from youtube. Ive heard mention of altering a ALLOW_HTML variable but that variable is no where in the config.pl

I know i can allow for other file types to be uploaded, but were dealing with potentially large files here, there is no need to double host them if they already exist out on the net. I just want my users to be able to copy and paste the embed code from youtube and when they submit the swf shows on the board ready to be played and seen.
