Et voila BACK TO FLARUM, it's already online IN PRODUCTION
I had a pause and IN LESS THAN 5 MINUTES I could fully restore FLARUM from my backup (another point in favor!)
You can see or test it at (please use the FLARUM tag)

Now I can resume my experience as site manager
1) ASP.NET + DOT NET NUKE
For several years I used the classical DOT NET NUKE as blog as forum
It's a wonderful product, but it's a general CMS so it's by force MAMMOTH and it grew and grew
Probably you know how strict is ASP.NET hosting policy about disk and database occupation
In brief, the cost became too large for the stage of my site at that time
2) phpbb
Then I migrated to Apache + php + mysql with one of the more classic solution: a phpbb forum
I kept it online for a couple of years, but the problem was the small participation
I don't know why, but I follow several hundreds of traders with my software system... and only few dozens used the forum, all the others used a direct mailing with me
3) Discourse
I payed a droplet to test the system, but it's very complex and rigid, beside you must use their resources for every customization (= pay, pay and pay)
4) EVENTUALLY THE END: FLARUM
So I found FLARUM presented as the best innovative and promising system, with a growing base and an active community
...and I can CONFIRM!
