[Mapping Lat and Long of caches found]

I'm looking for help in mapping my cache finds on line so I can get a picture of where the caches are that I have found. Similar to the state maps on the Geocaching.com web site. Any suggestions?

[Signature item ettiquette]

I'm quite new to caching (45 caches) and am trying to determine what to use for signature item. I have been leaving a business card but I'm concerned that it has to much info and that people may think I am trying to generate business when I am not. Any thoughts?
