1. Click at your own name, you will go into your personal page where you can log out and manage various kinds of thing there.
2. Yes, for example; if you want to sent me message. Just click at my name, you will go to my personal page. There's a place that you can leave the message there. Try then.
You can leave messages on user profiles (under the message board at the very bottom of the profile page) as long as you're logged in. I don't think there's a way to privately message someone if you're looking for something like that
1. Could someone tell me how to log out from the site, pretty please? I can't find this option.
2. Is there a way to send messages between users?
