Received a letter from RU-CENTER. In it, representatives of the latter are actively thinking about users, although they make their lives easier by introducing courier service. In order to suit everyone and everyone, they offer to take part in the survey (looks like this: "We think it will be a cool thing, how are we going to do? And what would you like?"). Of course, the courier initiative is rather tempting. Imagine, you do not need to go anywhere to re-register a domain or change the registrar. For a small gesheft courier in the amount of 300-500 rubles (the amount is not determined) any worries disappear.
Another thing is whether this will not be a reason for abuse or violation of the rules? At the moment it is said that the registrar should receive the original documents for actions with the domain - transfer of rights and change of registrar, or notarized documents. I doubt that the courier is a notary or a registrar. It turns out a small discrepancy, from which, most likely, they will get rid of with the help of some kind of power of attorney (you know these: “not to disturb the bearer of this and listen to aki the cardinal”). As for abuse, the system of operation of such a service is not yet clear, but the abuse can already be assumed.
Total - an interesting and useful service with proper organization. Note to the other registrars, definitely.
