There's definitely been a lot of transition pain, but what features do people like about the Reforge?
I’m feeling pretty good about the forums now that I've gotten used to interface. It’s fewer clicks to hop across forum topics, and it’s much easier to manually scan the posts since you don’t have to keep clicking to get to the next batch of ten. Big usability improvement over Preforge. Caveat: my campaign did not and does not use sub-forums.
I like the "last login" tracker on the dashboard. We're PbP. During Preforge, I had to manually search for a player's most recent forum post to figure out if I should send a participation warning. The "last login" tracker is a big time-saver and gives me confidence I haven't missed a more recent post.
