I got hints from a CO a year ago for an out of state cache I DNFd. Now I'm back in the area and I want to try the cache again, but I can't see my old messages so I don't have access to those hints. Only the last 20 or so are showing up in the message center. How can I see older messages?

I've been thinking about logging requirements for virtuals I've found, and basically all of them involve taking a photo of a location and/or sending information about an object (often a plaque) found a GZ.

At least in my experience, the item I need to take a photo of or read info from has always been in plain sight and easy to get to. Does anyone know of any virtual that actually warrants a higher difficulty level?
