It's always good to "get the lay of the land" before rushing in to something. A few free tips for you:
1. Always read posting rules at any forum
2. Read the forum, see who the members are, try to understand what they are looking for and what they would be willing to pay.
3. This is a forum for domainers, not primarily end users - set prices accordingly
4. Do some market research and see what your names are truly worth. There is an appraisal section, or you could post your whole list (in one post) in the "offers wanted" section. If you say "only offers over X,XXX" and you don't get any PM's or posts - you are probably priced too high for this venue.
If you really want to be a part of this community, it is a warm and welcoming one. If you think you are just gonna dump each of your names for X,XXX to a bunch of suckers, you wasted your money joining.
