Since I was probably one of the worst offenders (I am not going to admit how many messages I had)....
I just went in and did a big major PRUNE. Anything older than 30 days is gone. I started to read some of the old messages from friends who no longer post regularly and said, oh, I can't delete these...but I must. And I did.
And now I only have 116 messages. Phillip, you probably got 2 gb on me alone! LOL
