Hi Markus,

I am sorry that you had a bad experience with ovirt and I am sure 
everyone in the ovirt community appreciate your feedback and your 
contribution.
As you said, I am positive that you will be able to get it all managed 
and please use the list for any needed assistance.

I am adding some people to this mail so that they can help with the wiki 
request.

Thanks for the input!
Dafna
