Sorry to sound so grumpy bout this but I'm getting mail bombed off this guy's and Skitterpops machines and it's creamin me
Honest estimate I'd say I've deleted close to 1000 emails today already.....and I'm leaving for the shop right now, bet there will be at least 4-500 in my box when I get back tonite.
