Yeah, sadly, since integrating the forum into the site was a bit tricky, it doens't surprise me that it doesn't work perfectly on mobile.
The two workarounds that we'll have to use (unless someone volunteers to build a better website for free, yeah, didn't think so) include either going directly to the forum url which is currently located at smf.cdb-ottawa.com OR my preferred method which is using Tapatalk app. The experience through Tapatalk is incredibly better than using the forum in a normal browser, I'll never go back.
