While roaming the countryside I came upon this interesting question and also noticed very little reply from al you buzzin' bees.So is there anyone out there who has anything to say about this....?Rhodium perhaps....???
If you used TFSE, then you'd see there has been a certain bee in the past who was very interested in this topic. He has posted several references to useful articles.
