Subject [Solved - probably] Re: Need help with URL regex
Date Mon, 09 May 2005 00:43:44 GMT
Hi again,

I think I may have it working now. Not exactly the way I want, but I 
put this:

+^http://www.myorg.org/*

and

-.

and not it seems to just be picking up things from my site. But have 
not tried to put the ([a-z0-9]*\.)* back in.
