You know how when you post on forums, blogs, etc you link a variety of those web quirkiness items like "I'm 73% liberal.", or something like the Xbox gamertags found at mygamercard.net, or even if you want to link to a photo album from google's picasa - they provide you with code to 'share' your information.
It ought to be fairly easy to add some quick links to allow members of the site to share things such as:
-Scorecard (9 or 18 hole)
-A forum signature image that shows your last X rounds of golf dynamically
-What's in my golf bag
-Link to your profile
That would drive a good bit of traffic from people who use it and really enhance the social side of things.
And of course anything that allows you to do something similarly via facebook.
