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 else from robbing you with "@lock me=me".
3. set your gender, if you wish it known, with "@set me=sex:male" or "@set me=sex:female" (or "@set me=sex:neuter" to be an 'it').
