with the Lycos system, or with the software you're using, so I have one hand tied behind my back on this.
Page urls won't change in the browser which is what I think you mean) until the filenames are changed on the server. That means you have to change the name of the page files you upload to the Lycos website. It's the bit after the last forward slash that's important for this exercise.
If one of your pages is called: h t t p// w w w. /lycos users.co.uk/your name/about me.html
(I've inserted spaces to stop our site code turning my example into a 'click here' link)
and you want to retitle it to: all the same as before/moreaboutme.html you must alter it in the software and then upload the changed page file to the server. Then you'll see the new address in the title bar of your browser.
Does that make any sense at all?
