The word 'me' refers to yourself.
Some things to do when starting out:
1) give yourself a description with "@describe me=(description)", then look
at yourself with "look me".
2) prevent anyone from adding you to unwanted groups with "@lock me=me".
3) set your gender, if you wish it known, with "@set me=male"
or "@set me=female" (or "@set me=neuter" to be an 'it').
