I thought Jeremy used Hex for the numbering system. If so then when the number hits GC,16,16,16,16 (GCFFFF) then thats as high as it can go. ------------------------------------ i dont think it will end up being a problem.... we will run out of numbers on geocaching.com before we ever get to that problem... jeremy's current naming convention for caches runs out when we hit 65536 or GCFFFF caches .. and thats for the whole globe... catcha latz... jason _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com
