I myself returned to VGAP a few years ago after a long period of absence. As already said by others, this is probably the
place to be at the moment, with vgaplanets.dk being "definitely deceased" (to quote Monty Python) and rcworld.de having stopped hosting. The No Frills games here are mostly vanilla (i.e. a custom map and only a few add-ons that actually make sense but not much more) and are started fairly frequently. In fact, there's somehow a way to get notified when new games get started, so you should be able to join the fun soon enough.
Perhaps I'll see you around some time
