Newbie question - Add Contacts?

I've been reading a lot here since I joined, and definitely have found several girls that I want on my list, some 'newbie' friendly and some not. But what I was wondering is about the forum software. Is there a way to 'save' or 'favorite' or add to a watch list the providers I'm most interested in? I'd like to not have to rely on memory (I have no fucking memory) but I don't want to write a physical list either.

I saw the "Add Contacts" feature - is that for adding folk you already have a rapport with, or does it work for keeping a little black book of possibilities, like what I want?

Providers, do you notice when someone adds you to their contact list, and is it cool for someone you haven't met to add you? In my case it would be for finding you for appointments down the road.

I've never had a notification that someone added me to their contacts. I'm not sure if it's never happened or it just doesn't register as important enough to get an email lol

Got this sorted with Emily's help. Thanks!
