Is there a Discord or a forum I could go to with questions about the functions already available to use? I'm working on a fan project system for a setting on the website, but I'm trying to figure out the difference between the Ruleset page and Books page, and if I'm able to put in custom images for maps that I've had commissioned and so on.

I'm wondering if TTM can handle complex custom formulas? For example if we wanted to build a system similar to Alien RPG: Rolling uses a D6 pool which combines your Ability Score and Skill Score to find a total number of dice to roll. Then success is determined by how many 6s are rolled. Does TTM allow you to set up a formula like this or is this out of scope for this release? And secondly, given a non-fantasy setting, is there a way to hide Spells, Traits and anything else that doesn't apply to a more modern/sci-fi system? Thanks so much

Will my players need a subscription? For home brew to existing systems, will I be able to add new classes and base stats i.e. Will to dnd? Will I be able to add automation to my game?

Will a TTM membership also provide a RoleGate membership? If so, how will the different tiers relate to each other?
