I was hoping people could share some of the cool / useful features of certain registrars which might not be widely publicized? I'll start:
- NameSilo - sub-accounts
- Gandi - Free email / free basic site and blog.
- Dynadot - Free email forwarding / free basic site hosting / useful bulk domain search (1000 limit)
- Uniregistry - Can add domains from other registrars to see expiration & nameserver records.
