RegEx Help - URL Groups - Membership

I am trying to use URL groups to no avail.

I am trying to use a directory/.* regex, but it's blocked all.

Example:

Members/.*

What am I doing wrong (negative rule, block
"/members/.*"

Side note, with regex, can I make a generic URL group without using a full URL of the site (so I can use it in new blog templates) - Ie,

.*/members/.*
?

(i am trying to block members folder and all things behind)
