Borogove: PbP means Play by Post, aka Play by Forum.  It's not for everyone as it is slow going and requires daily attention.  Well, in theory/best case that's true.  In practice, it's nearly every day.  It's good for people like me who live in far flung time zones.

I look at table top/chat/Roll20 type games as feasting on your hobby every week or 2.  While PbP is snacking on it daily.

Kdtompos and any others interested: The site is called GotEXP and is owned by Misha Polonski whom you may or may not know from G+.

To me it's a game mechanic that doesn't ignore the players' relationship.

I'll be on grovelling for this, soon.
