FYI, GTA Brews does have a website where I post all the meeting dates and most of the happenings.
However all the discussion is on Facebook, yes. Many homebrew clubs (even in the USA) are moving to facebook groups because people would rather use that than a forum for the most part. It's where most people already spend time.
It isn't necessary to join on Facebook to attend the meetings or participate in the club, but you would be missing many of the best aspects of the club if you didn't. You are more than welcome to join us at Toronto Brewing Downtown on Feb 27th and any other club meeting/event.
I always try to encourage people to join on Facebook because it has such a lively discussion going all the time on several topics. I know several people that only use facebook for the group. You can treat it just like any forum, join facebook, join the group. One advantage is that the mobile facebook app is much better than any forum app I've used. You don't have to add any family members or friends as "Friends" if you don't want to. You could even create an account to use just for that if you have an old account you don't want to use, I know of several people that have done this as well.
