I second what Gothic says. Here's some elaboration on how I use the separate forums:
Regional forum - post your location/thematic specific explores here. (Informational, research based)
UE Photography - post your best and most exciting explores here. (Flashy, fun, attention and discussion based)
The UE database is something you'd dive into as a full member.
It's a maze of insanity in there that you only have open access to once you get that full membership. Then you can see if your location has been listed or not, and mull over whether or not you'd like to share your location specifics with the world.
How to get that full membership?
Start posting in your regional forum! I'm excited to see what you've been exploring
Take care out there.
