@ guka,
Do you remember,40 years ago,at the University of Marseilles. We attended a demonstration due to various administration issues. A photograph of you was taken by Pierre Jean as you led the demo and emailed to me and similarly he emailed mine to you as he was well aware that we were inseparable buddies. You were very angry indeed and your actions and determination clearly showed that if care was not taken someone would become a mogue statistics in the process.... Below is the photograph....
i surely miss those days...however as the undage goes 'Old is Gold'.,you needed not change the signature...it reminds ME alot..
NEVER TALK OF A RHINO IF THERE IS NO TREE NEAREBY - ZULU PROVERB
