Welcome to the OAC! We are hosted by Ning which has a standard formula for filling in a member's profile here and everywhere else. Most people only fill in what they want. We have a job persuading some to give their first and second names. So please leave out whatever you think is inappropriate. If you want you can drop the Sybil, but it's nice to know it.
I am not sure that it is either necessary or helpful to put a lot of information about oneself out when the aim is to discuss ideas. Why the date of birth for instance? I don't mind people knowing my age but does it help people to understand what I write? Perhaps to note that i am a dinosaur, one of the few remainging peopl who were taught by The Ancestors- Fortes, Evans-Pritchard, Firth etc. Enough.
