Thanks very much for your rapid reply, Lite, and I'm sure I didn't state my question understandably enough. Hey, I'm an English instructor--what would you expect?
Often specific examples enhance writing, and maybe if I turn my question into an example, I will make my query much easier to understand. Here goes: I want to try to sell a domain name I registered--MarryARussian.com. Can I try to enlist more than one domain name website--like Flippa and Afternic--to attempt to sell this domain at the same time.... In other words, I don't have to use just of these web sites at a time, right?
Somehow, I'm not sure I clarified my question sufficiently, but I'm hopeful someone will understand what I'm asking and help me to avoid breaking any domain-name selling regulations.
Thanks very much.
