I have to say Flarum looks beautiful and functions on the front-end beautifully. Unfortunately, since composer is required, I will not be trying it out for my website. I was looking around for a forum software that was simple to use, but, unfortunately Flarum will not be an option I'd consider because it has no basic installation outside of Composer. It's very unusual. I have a website that has a very high volume of traffic (servicing about 3 million hits a month), but, the need for a forum is so very simple. Flarum looked beyond what I was looking for.
It is extremely unfortunate that there isn't an easy way to install this beautiful and gorgeous software yet.
When I went to activate my account I got a invalid token error. This software does appear to be buggy. Please feel free to contact me once there is a semi-stable release candidate. I do not care about losing data on the forum between upgrades, but, I feel my website could bring some strong testing and it would've suited my needs flawlessly. If there's a SQL import guide, or workaround to Composer/SSH I would love to. I have SSH access, but, not Composer access.
Keep up the great work! I look forward to giving this a real test with my thousands of users.
