Just a small suggestion..
I noticed the forum is not using HTTPS to encrypt traffic to and from web browsers and phones and the likes.
In itself this is not a big deal, but it may open up some people to password sniffing, especially on publiv WiFi points and the like. (and of course nooooobody uses an important/same password on a forum or something like electronic banking.. right??? right...
There's a free option these days to get at least a base certificate for the webserver software that can help out and encrypt the traffic flowing between clients and the forum software:https://letsencrypt.org/
These guys run on donations/sponsoring so any money donated is appreciated and very useful but is not required.
