I looked at my email (my "real" email, not my Financial Rounds one) last week and decided it had gotten out of control - over 1000 old messages. I started deleting the old ones, but thought I'd never get it done - thee were just too many.
Then, I solved the problem by accident - I inadvertently ended up declaring "email bankruptcy".
I signed up for Hotmail's premium service a few years ago, since at the time it was the only one offering the capability of emailing large file attachments. The bill for renewal came due a while ago, and I forgot to renew it. So, Hotmail bumped me down to the "standard" version. In the process, they deleted all but the 200 or so most recent messages. Of course, this includes messages I received way back in 2006, so there probably wasn't anything I needed in the older ones anyway.
I feel much better now.
