I've setup a YAF/Sitecore Integration to play around with YAF

It's all working so far, next step will be to link it up to a different membership provider in addition to sitecore.

Whereever the Username is currently used in YAF (Eg: Posted By XYZ, User Profile Page (publicly viewable by other members), Members listing etc) I want to replace this Username using for example the Real Name field of YAF instead? (eg: right now it might shows sitecore\userA, or DOMAIN\userB)

Reason being the username cannot be shown in YAF because the membership provider username in this instance is required to be hidden always as a security measure

Is this a configuration change i can make it anywhere or would i have to edit all the affected areas and use the real name field instead of username

Thank you
