Okay, that was the only step I didn't try.
But sounds very reasonable. I'm testing it a last time with this interesting link for linking techniques.
And it works! Woot! Thanks everyone for helping!
I'm testing the html code since the the pretty (useless) A didn't let me do paste a text for my url.
<a href = "http://www.youtube.com/user/simonscat?blend=1&ob=4" >cat</a>
If you can't mod the script, try dragging it to your inventory and open it from there. If you've done your changes drag it back into the object. Happened with full perm scripts to me too sometimes.
How can I hide the url and write a phrase for a link here? That's all I want to know. I answered a question and couldn't nut Torley did it. I'm using Firefox 3.5. (didn't test Chrome or IE tho)
