For example, only organizations can register a “.org” domain name, and only American citizens can register a domain name that ends in “.us.” Failing to meet the guidelines and requirements for each type of domain during the actual registration and payment process will result in the domain name being “released” back into the pool of available domain names; the customer will have to pick a top level domain for which they actually qualify, or cancel their purchase altogether.
Yahoo Small Business services are intended and designed to meet the needs of personal and small business websites. This is why some of our plans offer unlimited disk-space, data transfer or email storage. It is not appropriate to use our services to support large enterprises or for levels of demand that impose undue burdens on our systems or negatively impact use by small, independently owned and operated businesses. If the bandwidth, data transfer or email storage of your website or email present a burden on the experience of other users or on our internal systems, we may, in our sole discretion, act to restrict the resources being consumed by your website, including by limiting how fast your disk space and email storage space can grow.
Many services offer so-called unlimited or unmetered service for whatever amount of bandwidth, disk storage and sites you use. It's important to understand that most terms of service actually do limit the definition of "unlimited" to what's considered reasonable use. The bottom line is simple: if you're building a pretty basic website, unlimited means you don't need to worry. But if you're trying to do something excessive (or illegal, immoral or fattening), the fine print in the terms of service will trigger, and you'll either be asked to spend more or go elsewhere.
