No, we are not. We have integrated the registration services of Public Domain Registry, an ICANN-accredited domain registrar, into our member interface to provide domain registration. Public Domain Registry enables us to offer great prices and, more importantly, enables us to support our members ourselves, all the way through the domain registration process.
We have on several occasions considered ICANN accreditation and decided against it. The development effort required to individually integrate different systems for each registry would significantly detract from our core mission to develop the best possible web hosting. It would also incur a lot of development expense and accreditation costs to recoup, which for a company of our relatively small size would most likely translate to several years of higher prices for domain registration. And yet, our domain registration service would be essentially identical to what we can already offer. Since the actual service for any given TLD is ultimately provided by the registry for that TLD, domains don't offer a lot of room for innovation at the registrar level. Charging significantly higher prices for the same service -- or, at best, maybe 1% better -- doesn't sound that great.
In addition to that, we sort of like our current position. With few exceptions, the domain registration industry is dominated by large players locked in a mortal race to the bottom of the barrel in terms of price and quality. They can and do make mistakes and cause problems for their customers. This is particularly visible in how they handle complaints. A billion-dollar company making a few pennies off of a domain didn't get to be that size because they keep a team of lawyers on standby to scrupulously hold every complaint about every domain to the highest legal standard.
If your registrar makes a mistake or a dumb decision... and they all occasionally do... you probably won't have their entire executive & technical staff on your contacts list. We do. And if we agree it's a dumb decision, we do not hesitate to use those contacts to "advocate vigorously" (and typically very, very effectively) for our customers on those rare occasions when things go awry. In fact, our registrar has learned to contact us with complaints about domains registered through us before they do anything, rather than after the fact, so we've even been able to head stupidity off at the pass more than once. Don't underestimate the power of having an 800-pound freedom-loving gorilla in your corner! (But don't overestimate it either. Public Domain Registry isn't perfect; no registrar is. Although it's extremely rare — like "count the cases on one hand with fingers to spare" rare — they do have the right to handle a situation in a way we disagree with. And, of course, if a domain gets suspended or canceled for good reason, the gorilla is totally fine with it.)
