Thank you. If you like GNU Parallel:
* Give a demo at your local user group/team/colleagues
* Post the intro videos on Reddit/Diaspora*/forums/blogs/
Identi.ca/Google+/Twitter/Facebook/Linkedin/mailing lists
* Request or write a review for your favourite blog or magazine
* Invite me for your next conference
If you use GNU Parallel for research:
* Please cite GNU Parallel in you publications (use --bibtex)
If GNU Parallel saves you money:
* (Have your company) donate to FSF https://my.fsf.org/donate/

Your bug report should always include:
· The error message you get (if any).
· The output of parallel --version. If you are not running
the latest released version you should specify why you
believe the problem is not fixed in that version.
· A complete example that others can run that shows the
problem. This should preferably be small and simple. A
combination of yes, seq, cat, echo, and sleep can
reproduce most errors. If your example requires large
files, see if you can make them by something like seq
1000000 > file or yes | head -n 10000000 > file.
· The output of your example. If your problem is not
easily reproduced by others, the output might help them
figure out the problem.
If you suspect the error is dependent on your environment
or distribution, please see if you can reproduce the error
on one of these VirtualBox images:
http://sourceforge.net/projects/virtualboximage/files/
Specifying the name of your distribution is not enough as
you may have installed software that is not in the
VirtualBox images.
If you cannot reproduce the error on any of the VirtualBox
images above, you should assume the debugging will be done
through you. That will put more burden on you and it is
extra important you give any information that help.

There is nothing in what you do, that seems to be wrong. But there may
be something locally on your machine that prevents it from working, so
please try it on a VirtualBox. And please include a complete working
example. If the problem also exists on the VirtualBox I will be able
to reproduce your problems.
