I found this game on a local forum, and think it could work well on Gransnet.
Rules: 1. Player posts a long word. 2. Next player makes three words from the long word. 3. Then makes up a sentence using the three words, with preferably at least 3 letters. 4. Posts a long word for the next player.
So, let's play
INSURGENT
gent surge grin
She felt a surge of happiness when her gent came through the door with his usual wide grin.
