I checked a discussion in one of the moderators forums that we had on requiring real names in the registration process.
It was decided that, for security reasons, we would not require real names in the registration process, however, it would be nice to know whether or not we are posting to a male person or a female person.
We may require the use of a persons given name in their post or display name which should still protect their privacy and security.
In the meantime, things shall continue as is for the time being.
