Sure it is.(posted 9795 days ago)Go to http://marp.retrogames.com/ and create a new account. Just click 'enter', then 'submit' and it'll ask you to log in. Click 'new user' (or whatever it says) and it'll ask you for details. Then it'll give you a URL to bookmark. Click on it, then add bookmark. The bookmark should have the new user's name as part of it, so you'll now have two different bookmarks.
Good luck!
