300 games have been played at Online-Scrabble now, not bad is it?
In a little over 1 month there's been 160 members, that's almost 2 games per member!

The most popular is traditional surprisingly, I honestly thought it would be Never Ending:

Traditional: 194 games
Never Ending: 66 games.

But considering Traditional can be played an unlimited number of times, and Never Ending is 1 time per member, I suppose it makes sense.
