If you find a post helpful please use the thanks button to thank the helpful poster.
(and don't thank them if its not

)
It makes them feel wanted and makes it more likely that your questions
will receive more attention from the helpers (shallow lot that they are) next
time you ask for help.
Also don't abuse the system by forming cliques giving one another thanks for
trivial of non-existent help.
