This only really works on small roleplay sites (in my experience).
Basically, my idea was that we could have site-wide events and co-ordinate a massive rp or a bunch of small ones that are all themed around said event.
We could convert the normal holidays like Christmas or Valentines Day or Halloween and make them into like site wide events.
Or we could just make a giant poke-crisis.
Whaddaya think?
If I'm crazy, it's totally okay. :D
