TN, LN, and SL (Took Nothing, Left Nothing, and Signed Log) are often combined together in various ways to indicate that a Geocacher signed the log, neither dropping nor grabbing anything from the cache. The acronyms are a very integrated part of the geocaching culture.



The TFTC/TFTH DebateEdit

These acronyms often find their way into debates. The debate centers around situations where a geocacher logs a find and says nothing in their log beyond the acronym, such as "TFTC!"  One side of the debate finds this rude, particularly with geocaches that require more work to find.  The idea is that if a geocacher spent time putting together a cache for the finder's benefit, the finder owes it to the hider to take a few minutes to say a little more than TFTC. 

The other side of the debate is that some geocachers use TFTC because they are logging a find from their phone, with the intention of updating the log at home on a computer.  With the ease at which geocachers can now log finds using geocaching apps on their phones, there has been an increase of TFTC logs.  Since cache owners receive Log Notifications only from the initial log, and not any subsequent edits, they might overlook updates to that log in such a situation.

It is also often pointed out that if a geocacher finds a geocache that they were unimpressed or even annoyed with, they may have logged it with nothing more than TFTC as a way to avoid saying anything negative.
