I've seen several questions on the coordinate format used to search the wap site, but I haven't seen this particular issue addressed:
The "Search by: Coordinates" screen takes its input in decimal degrees (ddd.ddddd), but cache locations are in (-)ddd mm.mmm format.
With my cheesy little Garmin eTrex, it takes a whole lot of button-pressing to show my current location in the query format, then switch back again to enter coords in the results format.
Because it is a lot harder (and more error-prone) for the site to have to parse multiple input formats, it would be easiest if it caches were displayed in multiple formats -- ideally through a user setting.
