So I haven't known about Flarum for very long, I happened to come across it while browsing the web in my class. I think it looks very promising and I can't wait to get an install of my own up and running. Unfortunately I have a very limited programming experience (I'm a designer after all!), and kept coming across errors in the Vagrant installation that I wasn't able to track down a solution for!
So I'm really looking forward to the betas and being able to test it out myself! It looks wonderful!
