Any particular systems I have an interest in are on my home page in the My Radioreference section.
I think that's really the answer. I had a similar wish before I registered a few systems of interest on my RR home page. That simple act takes care of at least 98% of the 'problem' for me with respect to watching for database updates.
That said, I
do wish the main forums page had a simple way (such as one line of A-Z links based on the first letter of each state name) to quickly jump down to at least the vicinity of the state forums I'm most interested in. A nit, for sure, but it would be a nice addition that doesn't sound at all difficult to implement.
Thanks to everyone who contributes to making RR such a useful site, whether through administrative help, money, database donations, forum contributions/moderation or other ways! It's really impressive to see so much useful information in one place, with so little bureaucracy.
