I am a complete newbie when comes to coding. I'd appreciate very much the help.

There's this WordPress plugin where you cloak your links (the plugin here --> http://bit.ly/13AYpUF).

It redirects the link using this model: websitename.com/go/username

I want the name in the link instead of "go" to be "list" -- like this : websitename.com/list/username

(p.s. instead of the name "list" I may choose a different one.)

I tried myself to replace within the code the name "go" with "list", but after doing this, when clicking the link it showed a 404 error page.

Thank you VERY much!
