Welcome to the Guild, Rithy!
Glad to see you're enthusiastic about joining. I hope to see you wandering around here some time. If you happen to have any questions about the forum or need some help getting around, feel free to ask me or one of the other Comrades. We're the users with italicised usernames, and we'd be happy to lend a hand if you need it.
If you're looking to get started nice and quickly, I'd recommend starting with the Guild's Guide. It should answer most of your questions.
