**I didn't see this topic anywhere else yet, if it already exists then I will move this post over to it.**
I had sent in a couple of suggestions to Geocaching and they said to post a forum thread, so here it is.
1. Ability to search for a user and then be able to submit request for "friendship" after locating them
2. Ability to have more than one home location to watch and receive immediate updates on new caches. For example, my girlfriend and I cache a lot now and we live in different locations and also work in different locations, but we both use my account. It would be nice to be able to receive an email for several zip codes whenever a new cache pops up.
3. This one ties into the one above, the ability to have more than one email address the can receive an email on new cache listings.
