Hello,
I wish to acknowledge publicly the kind help of Dr. David Campbell. I am
also sure that many other people would like to help too (if Unionids are
lesser difficult), so thanks to them in spirit... Thatīs why Iīm here, you
never let me down.
Hope someday I could do the same for somebody of you, meanwhile, I have so
much to learn still...
Yours,
