I had my domain (j3dm.com) registered through DYNU. Thier service was horrible to begin with, and now they appear to be gone.

My registration expired last month. I could not renew because they I could never reach them. Now my domain appears to be grabbed by someone else? Tucows?

Please give me some ideas of what I can do from here other than just choosing another name.

Contact Tucows/OpenSRS ASAP before the domain goes into the redemption period. DYNU appears to be a Tucows reseller.

Yep, already made contact and there is some work to do as the registration is tied to my "old" email address. Under control now though. Folks at Tucows have been very helpful so far.

Glad to hear your moving towards a happy outcome,
I wish we heard that more often.

Too bad... Hope you get your domain name :) Steer clear of small time registrars, IMO.
