Maybe you have seen that there is currently a campaign to award each
other with barnstars on the wiki here:
We currently have very few awards on this page but I'm sure there is
somebody you want to thank for some help or some work he/she has done in
your area or in your team.
So don't be shy, a 'thank you', whatever the form, is always something
we are happy to receive
Thanks a lot in advance for your participation!
