Another request to enhance the site: feedback options regarding the cache at the moment you log your visit. The two following ones seem to me the most usefull: 'surroundings' (is the location of the cache nice ?) and 'used techniques' (where there fun techniques to use to get to the cache, like riddles, microcaches, etc. ?).
In practice I see it as a 6 level choice: No Comment, Very Bad, Bad, Neutral, Nice, Very Nice; with No comment as default. For each cache the feedback can be aggregated to show an average score (so if only one person ranked it as nice -> 4/5). The 'no comments' aren't taken into account in order not to bias the results with the 'no feedback' of those not willing to complete it.
As a last option, you could implement in the search a 'more than ... score' to find a cache for the two feedback options.
Hope it gets realised once...
Alpenmarmot.
