I'm not sure why an automatic purge would be needed, just use a simple LRU
algorithm like a cache would use and let the least requested grids fall into
oblivion.
I still think "most wanted" is based on region. Most wanted grids for the NE
USA are probably different that most wanted grids for the SW USA or Canada, or
Europe, so some sort of correlation to the requester grid needs to be made so
that clustering can be done, i.e. operators in grids around FN42 are
requesting FN52 (of which there is no land, completely in the Atlantic), while
operators clustered in and around grid DN17 are requesting DN28...

Mike asks How can you have a voting scheme if you are keeping old data?
Without some type of a time stamp filter wouldn't that sway the results? And
if you are going to filter the data with a time stamp wouldn't an automatic
purge of entries after a certain time period be equally as beneficial? I'm
asking because I am not a database person, much beyond html & css I'm pretty
useless anymore. I'm sure that EL84 just dropped significantly and would
not change if those who ha
d requested it didn't remove their request. -- Mike Urich KA5CVH
