 I must reply that we are all beginners, who amongst us can consider
themselves an expert. I do know many who claim this but it's a fool who
would boast "I know it all"...
The wisest man once replied "I don't know, teach me "
Please don't take this as an insult , I 'm just stating that we all have
much to learn and if using common names along with Latin names helps when
communicating with others then this is beneficial to all concerned.My wife
says that she considers herself a beginner as she learns something new
everyday. mark
