Sorry if this has been asked before, but...
When placing a cache, should I quote its location using the WGS84 or OSGB datum?
I know that there's a note on the GC website which says 'WGS84'. However, in my experience, I find other people's caches with my GPSr set to use OSGB datum, which makes me think that the convention amongst British cachers is to use a datum which makes more sense in relation to our OS maps.
Which is the correct option?
