The site's a tiny bit confusin, explanations please?

Yo, glad to have someone new on board! Sorry if the site is a little bit confusing, it was the same way for me at first.

To make a character usable, go to 'Player Profiles', and choose which moon you want your character to have been on in their native session. (This means their first session, not the one you want them to play now) and make the character sheet for them.

(http://sburbunofficial.boards.net/thread/11/profile-base) This is a profile base for a character. You copy/paste the BBcode at the bottom and fill in the blanks. If you need help with BBcode just PM me and I'll be happy to help, as would everyone else on this forum.

After you have done this, the character is ready to be played! The character list is where we put all of the names of the characters we play to help keep track of people who play multiple characters.

If you wanted to make a new session, yes, you just make a post in the session list following the guidelines, and you can make an IC thread for it. It might be helpful to pop into the OOC Discord chat to ask around for people to participate in the session before you make it, however. Here is a link to the Discord: discordapp.com/channels/181275740745105408/181275740745105408
If for some reason this link doesn't work, I'll post a new invite link later, as I am on mobile right now and discord hates my phone.

As for making our own Aspects and Classes, that's a bit of a tricky subject. We use all of the ones from the Glitch FAQ, as well as a few others. Generally, the rule for making new aspects or classes is no. However, if you think you have an idea good enough, you can present it in the OOC chat and we can discuss it there. I would recommend having a plan of how the aspect/class would work and how it fits into the existing canon. (One recent example of this is the aspect of Dust, which previously existed and was represented in a new light by one of our members some time ago.) We support the integration of new ideas, (and implement new ones almost daily) but as a rule we try to have somewhat of a communal agreement on what happens, so ideas don't get too out of hand.

If creating aspects or classes isn't your thing, their are always things to do for the existing ones. You could write a guide, or make art, or create other such peripherals.

Tl:dr that was a wall of text. Short version: hop on OOC chat and we can better answer your questions there. Glad to hear you want to join the community, and we are really glad to have you!
