Caveat emptor

Care should always be exercised when registering a domain name: DNS is case-insensitive and the modern trend of words run together with intercapping can be misinterpreted when converted to lowercase. Who Represents, a database of artists and agents, chose whorepresents.com; a therapists' network thought therapistfinder.com looked good; Experts Exchange, the programmers' site, for a long time had expertsexchange.com; Another website operating as of October, 2006, is penisland.net, a website for Pen Island, an online pen vendor.

In such situations, the proper wording can be clarified by use of hyphens. For instance, expertsexchange.com changed its name to experts-exchange.com.

DNS is case-insensitive, so such Web sites can also be further clarified by advertising them with proper capitalization. For instance, TherapistFinder.com.
