I am new to geocaching and only have 48 founds and 2 DNFS ,but on two of the founds the log book was either full or soaked so I added more paper after signing it ,and in the case of the wet one I added a sealable bag , both times I added a comment in the log to reflect this , but I counted them as found ,the two dnfs were logged as I didn't find the cache on one and didn't sign the logbook on the other due to muggles but I did find the cache ,but I logged it as a dnf because at the end of the day I would be cheating myself
