Filter: Log match

GSAK (Geocaching Swiss Army Knife)

And log is by a certain person (Search=>Filter=>Logs)

Use this area when you want to limit the logs to those of a certain person. You have 4 methods for matching. These methods are exactly the same as for matching your placed caches. If you want to match on more than one person, enter each one separated by a ; (semi colon). Also see phase 2 of the log selection process.
