the new site I am about to build requires user to login in order to make a comment on given article, however, these members should have nothing to do with the backend, in other words, I do not want them to see any part of the cms area. in addition to this, if admin update some article in the cms - ie published some new article or updated a existing article, these member will get a email notification about the change. These members may also update their profile. (can it be done in the front end?)

Is this possible? I had a look at the following documentation http://doc.silverstripe.org/doku.php?id=recipes:forms
it explains how to create a simple sign up form. I am wondering how do I set the group ID or where to set it? do I just pick a none-existing ID for the grounpID say '10'. Will this group member be able to login to the backend?

Could someone point me to the right direction please.
Thank you for taking the time to read this!
