ICANN just emailed me their yearly whois check-up, reminding me of a domain I own but forgot about. I had registered the domain via dot5hosting. To transfer the domain, I emailed dot5:

I would like to transfer ischemic.org to another registrar, but do not know my dot5hosting.com login information. Do I manage the domain through dot5hosting.com or through opensrs.com? Otherwise, would it be possible for me to initiate the transfer at GoDaddy.com and then get a confirmation code from you?
