You can save other members for various reasons, and this is all done via the save link on his profile.
Open his profile and click save (top right). You'll get a pop up window with a 'mark as' pop up menu Select one of the 4 options.
- '-' is the catch all option if you just want to save notes on that guy.
- 'hottie' if you think he's hot. He'll be informed (unless you turn on 'keep my hotlist private' in your settings and that save will be used to decide whether he gets to appear in the 'popular members' section on the HOME page.
- 'my buddy' TBH it's no different from '-' above.
- 'blocked' if you no longer want to see/contact that guy and don't want him to see/contact you.
All 'saved' options also allow you to save notes and the private content password for that member, (if he gave it to you). If you're a supporter the saved password will be entered automatically, and you'll see his private content whenever you visit his profile.
