I think that compliling a list of 'patient expert' is far from a good idea for many verious reasons..
This is an informal forum, where it's basically a group of diabetics sharing there experiences of living with diabetes, sharing information on what and how we control our diabetes day to day, that gives us good control...
The forum deals with a medical condition, not the inner workings of a computer, and what is the best graphics card or the better processor where the notion of an expert can acutally fudge verious lines, but if an individual isn't as 'expert' as they feel they are, the damaged is basically limited to the listiener, a naff computer, broken computer and out of pocket..
Here information given by those who think they are 'expert' but fall below this, actually could be doing someone physical harm, leading them either into life threaten short and/or long term dangers... The criteria that you are suggesting is far too basic indeed, and open to abuse in many ways..
Would you really want some-one PM'ing/e-mailing you and saying, I'm the mum of little Johnny, and I asked this question on your fourm as little Johnny was having a bad time, your 'patient expert' fred bloggs told me to do this which I did, after all they are as you say an 'patient expert' but now little Johnny is in ITU and they not sure if he will come out of his comma that he's been in for the last 3 weeks, since I followed the advice of your 'Patient Expert' A very far cry from a nasty pm, saying I followed your 'expert' and bullsied up my computer!
I feel the more we keep away from giving the preception of 'experts' within the forum will ensure that visitors and newbies will realise that it's informal, as we are dealing with a medical condition a perception that 'Patient Experts' are the same as our helath care medical experts who have medical quailifications to underpin there knowledge... We don't all we can say is that we are expert in the day to day runing of our own persoanl condition...
