Bantha, it's quite easy to post youtube videos here on the forum.
In your address bar of your browser window, each youtube video will end with 'v=.....', copy the letters and numbers after the =
Then reply to a post on the forum using 'go advanced' (at the bottom of the page) and there will be a little youtube button in the icons.
Click this and you will get youtube 'tags' appearing in the message.
Paste the letters & numbers from the video you want between the (youtube)(/youtube) tags and your video should appear when you post your message.
I've attached a little picture just to show you.
Hope it helps!
Anyway, was this the band you mean- ljusår?
