Bodis.com is an excellent option in my opinion and i'm sure you'll find many who agree :imho:
Bodis has a approval process and is i bit backlogged at the moment but it is worth waiting for
Other options are:
Sedo.com - no approval process.Just create a account and park your domains,Has it's pros and cons.Great if you want to flip your domain but unless you have excellent domains,you probably won't make much from just parking.Uses a google feed.
Name drive.com. - no approval process as above.One of the better parking sites and they have excellent customer service.Uses a google feed.
Goldkey.com - approval proccess and approval of any individual domain after joining.Uses a yahoo Feed.
Parked.com - One of the better parking services.Need ten domains for the approval process but you have that covered.Uses a Yahoo feed.Lots of happy domainers with Parked.Donny regularly posts in the Parked.com thread here in namepros as to keep everyone up to date.
Doamainspa.com - no approval process that i can remember and if i recall correctly they use a yahoo feed.
Those are the ones that i have used in the last six months.All have their pros and cons.There are other,bigger parking providers like Skenzo,Trafficz,and fabulous to name but a few,but you need a minimum amount of domains(i.e. 50-100) or huge amounts of traffic.
If i was to order my preference, it would be.
Bodis
namedrive/parked
goldkey.
That's just my opinion though.You will find that different domains do better at certain parking providers,so initially i would suggest moving a few around to different places and find where they work.
Good luck
As far as parking your domain,after you have chosen which one you are going to park with first get their the nameservers that you have to point your domains to.These are usually found somewhere on their homepage or in your account confirmation email.They should look something like this:-
NS1.BODIS.com
NS2.BODIS.com
Just as an example.
You then go into you enom/go-daddy account,log-in to your account.From there,go to the section marked manage nameservers,remove the default servers and enter the name servers that you want your domains pointed at,whether it be parked,namedrive etc.etc.Then hit submit and you should have successfully changed your nameservers.You will get "changed name servers successful" message or something along those lines if you got this right.
I hope i haven't missed anything but if in doubt ask other members on this fine forum.I have found the majority of them to be quite willing to help people new to all of this. :imho:
