Thought I'd throw out a tip that others may already be using but I just figured out; watching domain name expiries!

Although my GoDaddy account auto-renews all my domains, it's still handy to have an annually repeating event to show billing days. But the main priority for me is to add expiry dates of domains I'm interested in poaching if the current owner no longer wants them. I simply added a new list ('Domains') and then added events for each domain I'm interested in. I made them due on the expiry date, which can be grabbed from a simple Whois lookup (http://who.is for example).

Hopefully someone finds this useful! Thanks, Benjamin
