Hi Petra.... 
 
Yes its great this thread, cant wait to get stuck in, so i will be doing alot of rambling for a while.... i must think of some questions.....a 1000 looming.... 

   Dont know who is going to answer, i know there are a few folks here who have great knowledge... i will get back here soon....
Im trying to think of a question now but cannot, need some sleep.... 

   Just finished a college course today, Im now a teacher.... 

   You know the saying, 
"Those who do, do.... those who cant do... teach...." 
 
With Love 
Sarah xxxx
