转移.cm域名的大坑
转移了一个 cm域名到一家国外注册商，转移很快，可是我发现到期时间并没有延长一年。于是我发了ticket给客服。客服的回复：
Thank you for your message, we have written to the registry to resolve your request more quickly. We will notify you as soon as we receive a response from the registry.没过多久，他问了注册局，回复：
The registry does not provide free renewal during transfer like other registries. Expiration date will not be changed.后来我谷歌了一下，发现不止.cm域名有很多域名都有这个大坑，参考：
