I've seen mentions of an "X-marks card" in several posts. I'm assuming that some carry a business-style card that they can pass to interested persons so that they don't have to search for a scrap of paper to jot down the web address. Sounds like a great idea.
Are there examples posted somewhere for us to follow if we'd like to print up some cards? If not, what are some suggestions, other than of course the title and address?
