There's a separate App for here; Garage Talk, which you should be able to find in the app store/Google Play. It seems pretty easy to use, but I'm used to using Tapatalk for all my other forums/groups, and it's not available there. No idea why.
Owners of this forum rely on the most limited function they can find. They don’t want to be bothered re programming and updates or general maintenance. Occasionally, Terry will see it in his heart to contact the owners and request a revision to help get the forum out from the ******* it ended up in. Usually takes a while tho because the owners live in gemany and are too busy enjoying their beer
