I 100% recognize this site in new and evolving, however I think it would be awesome for you to get a new user or someone with basic understanding of discourse to create a fresh account here and try and run through the site.
Get them to note anything that needs clarification and anything that they can’t do.
As a final step build out a big ‘help’ doc with solutions to the problems experienced by your test user for others who are just coming in.
Getting off topic now but two ‘problems’ ive already found is I can’t post in most topics here nor can I find any of these tutorials for the site that the badges are telling me about. If you had a test user building your help docs I think the ‘new topic posting’ problem would have been solved. It could just be me not verifying something in my email but right now I don’t know
Hope it helps!
