Correct me if I'm wrong on any of this, but wouldn't it be...
If each member DID write the full 160 character, that would be 160 bytes... That times the current member count at the time of this posting, 3325.... 532,000 bytes, which would roughtly equal around 500kb (I forget how many bytes are in a kb exactly). That's not too much space, not even a megabyte.
