TrueStar Domains

What would you think is a very good or the best place to put domain names for sale?

Many thanks!

I have 2 domain names and I want them to be hosted by a different register. Transferring them seems like a real pain. If I cancel them how long do I have to wait until I can buy them again?

I have a registered domain name which I use for my web site. My question is, can I obtain/register another different domain name and use it for the same purpose, my web site. In other words, both would lead people to my web site.
I’m unable to find any information on yahoo if this can be done.
I would want the other domain to actually BE my business name, so I assume they don’t have to be similar as long as it is not used by any other right?

I have a few domain names reserved and I have been getting bounced emails coming to them which supposedly came from my domains but in reality are sent by spammers. How can I find who the spammers are and what can I do about it?

(they do that for free) I tried my .tk domain and my .co.nr domain. but its not working! what free host do they support so i can get a free .com or .net domain ?
on yakkel.com you can get a free .com or .net domain if you had one from before. im asking for other redirects that affiliate with it. durr

There are so many different sites that offer registering domain names and website building but some are oddly cheap and some are off-the-wall expensive. I am looking for answers from people who have actually done this before. Thanks!
