Guests are not useful at all. Why are guests allowed in chat? I have many points to make about why guests should not be allowed in chat.
1. Guests aren't allowed to talk, so what is the point of guests being there in the first place?
2. Guests are given random names each time they log into chat. This means they can just refresh to add more and more users to the list, spamming chat.
3. Speaking of having that many guests in chat, chat gets locked at 100 and no registered users can join until they are kicked, or until 30 minutes pass by for a timeout. (By the way, reduce timeout to 5 minutes because there's no reason to have timeout at 30 minutes)
4. It only takes a minute to sign up, and it's free, and allows so many more benefits from the site. Sure, keep allowing guests to play the game as a demo to what they get before signing up, but disallow chat for the obvious reasons of it's free and it's fast.
Vote "Yes" in the poll if you believe guests should be removed.
