No worries! I've only been on here for a bit, but the people are pretty friendly and helpful, and I would really recommend joining the discord for stuff like asking questions and just talking if you're interested. Other than that, make sure to check out the guidelines for all the essential stuff, and you should be good.
If you got any questions feel free to ask. For quick answers I suggest joining the Discord like Nobuya said. People are very helpful on there and more than willing to help out. Saga and the rules can feel daunting at first, but they're relatively straightforward.
