TP 3.2 web users question

I am not sure how web user and group assignment work but I am not able to get it to do much.

I created a new web user from the back end, I create a new web user group and document.

I was able to assign document group to the new web user group but I am not able to assign a web user to a web user group.

I am also not able to signup as a new web user via the "WebSignup" snippet. The registration process went fine but I did not receive any email or the registered user name show up in the web user listing.

I don’t see this setting in my version my Modx.
4. Next, Select the user group you want the user to have access to:


What am I missing here?

Thanks

I think you need to enable Access Permission from the System Settings screen

That did it!

Thanks
