I have thought about this idea before, but this may give the impression that a member of the sangha who is less than 'noble,' 'knowledgable,' or 'expert in an area' has more knowledge. . . than they actually have, and give a potentially unfair, or unwarrented authority to what they say, even if what they say is wrong. this could mislead newer members or members who do not have a clear understanding or simply knowledge of the topic or issue being discussed.
I know of one issue a monastic here did have on a forum because he did not wish to use a image of himself as his avatar, and a similar problem could happen, do the rules then include an opt out for those who do not wish to be made to appear different to other members for whatever reason? and would this then cause another version of the above with newer members . . . paying more attention to one monastic over another based on the colour of their name?
although I think this idea has some plus points in some cases, it does have a very big down side to it, and posible unnecessary work for the admin & mods.
I personally am very grateful for the input of the Sangha members currently here no matter what tradition or liniage they belong and hope they continue to contribute in any capacity they can, but I would not like them to be put in a situation where they may be seen in a light which distracts from the validity of an argument expressed by another, here it is the posts that matter not the title or position within this online community.
He who knows only his own side of the case knows little of that. His reasons may be good, and no one may have been able to refute them.
But if he is equally unable to refute the reasons on the opposite side, if he does not so much as know what they are, he has no ground for preferring either opinion …
He must be able to hear them from persons who actually believe them … he must know them in their most plausible and persuasive form.
