@dansup If you're seriously considering moving to that type of format, I've found @nodebb to be quite lightweight and easy to install and launch. I did have some initial federation issues but that ended up being my own fault.
@incentive @dansup #Discourse has a passable iOS client, though. There's #Tapatalk for #NodeBB (I believe), but I'm not sure you'll want that in this day and age.
