This is not enough information for a mistress to want / take you.
First you need to post your ad in the personals section.
You need to provide more information so a potential mistress would want to take you.
Here's some things you should include:
Talk about your history. Are you a new slave or have experience? If you have experience talk more about what you have done.
If you have limits post those as well as will will be asked about those at some point.
Mention if you will/will not take pics, go on webcam.
Ways to contact you (if you want something other then the forum or private message on here)
Length of time you wish to be a slave with the mistress (ex I am a college student so I can only be owned/ do tasks during my summer break/ other breaks)
Possibly a little about yourself
