altering a link

[Lonefirewolf]

I need to know if there is any way that I could create an entrance box, for a link, that would change on part of the link..
What I'm trying to do is change the "User" part of that link, but leave the rest alone.
http://chat.teenchat.com/optichat.html?oc_acc=teenchat&oc_stage=2&oc_room=Test+ Room&oc_dyn=&oc_user=Blah+Blah&oc_syspass=0

I'm not sure if this would be Java script or not. I'm using this to put a chat room on my site

Thanks

Hi everyone,

I think this is a Java Script question

Would be the correct way to set up the link
