selling domains the right way

I have 3 domains registered with namecheap I am wondering how and where i can sell them. namecheap tells me that the only way they can be sold is through them if I do a domain transfer are there any better ones..

I wish i could post the sites I think there pretty good but for somereason in the section "site flipping" you're not aloud.. first is a net last three are com's
cleanmycomputer
tech-mods
flippedonline
dealingwithmiscarriage

any help is appreciated !

clean my computer is ok, the rest suck though. certainly not high enough quality to break the rules. you should check out my free site (dailylist [net]) for daily parsed pending delete lists. shouldn't be against the rules as there are no ads, its a one page site with a table of 5000 domains....
