Hi,
Well only from my own experience, I never wanted to find a Dom through "advertising" Whether it was in a chat forum, or on sites more directly situated towards a specific area, I was able to get to know Dom's through their discussions and often watching interactions with others. So my best advice is be yourself, as cliche as that may sound. Join in discussions, let submissives and others see all your sides. I've so often seen people turn up their noses at sections as the fun and games one here, or sites with blogs or off topic forums, but honestly these are the places I've learned the most about people. They have far more often led to PM discussions and/or just discovering that someone is extremely interesting and wanting to learn more.

This is just my lowly lil opinion, and surely there are others with more specific opinions...wishing you well, enjoy the journey and not just the destination!

hugs!
cali
