I'll be keeping an eye on outgoing email for a while, just to make sure we have a good idea what our outgoing volume is.
To all: If you're getting too many emails (some of you appear to be "watching" multiple threads, which means you get an email any time anybody posts in those threads), you can control that by 'tracking' a thread rather than 'watching' it.
With regard to the digest email - digests are sent when you have not visited the site (logged in - if you browse the topics without logging in the board has no idea you were here - duh!). In your settings, you can control how often digests are set - from daily (most frequent) to once every two weeks (least frequent). If you're not a daily visitor - think about how much email you want!
