changing name - am I going to be blacklisted ?
 

My first website was a celebsite - figured out that it wasnt the way to go, but I kept the name and used for hosting my free sites. i1 nov its going to be renewed and I desided not to pay for it any more and choose another name.
So am I going to be blacklisted for that ?

noooze

Just let the sites that have you listed know you should be just fine :)

If you change the domain name, none of the links going to your sites will work any longer - so at the least, you'll have to resubmit them again or ask that the link be changed.

Someone will buy your domain and redirect any traffic that you had coming to it.

Do yourself a favor and spend the few dollars to renew it.

If you want to start using another domain that is fine. Just point both of your domains to the same server. No traffic lost, and now you have two domain names for the SE spiders to chew on. :)

I agree with Cleo (again??)
Just renew the domain for 15.00 or so bucks.
Then simply start submitting with the new nick.
