you know my friend ....... in every thread with valuable information i always tend to thank the writer and add a comment.
but when i write a thread and/or provide a valuable information .. i dont see much people clicking on thank you button or bothering them self with writing a feedback wither it was successful to them or not ...
im not saying all the members but most of them....
thnx for spending a valuable time of yours to write such a thing 
... very sweet of you.
