This forum is part of the discourse platform and there’s a pretty routine system for going from the first user level (0) to the next level and then beyond that. It’s mostly reading posts and doing a few specific things, it might be easier on you if you take a look at this. If you want to be active on the forum, it’s just helpful knowledge to have going forward. It won’t teach you everything, but at least to have knowledge of basic leveling up is pretty useful as a new user so if you have time you can check it out here:
