No one needs our permission to host an event. They do need permission to use the Joomla! trademark in the name of an event.
No one needs your permission to use the word "Joomla" in a conference name.
There are many examples of other conference names available all over the planet.
A perfect example right now - The O'Reilly MySQL Conference & Expo
The 2010 conference is not co-sponsored by the MySQL camp as in previous years.
You will notice there is no use of the trademarked MySQL logo on the conference website.
Simply using the database name MySQL is fair use and not covered by trademark law.
MySQL has no legal right to require permission to use the word MySQL in the conference name.
Obviously there has been some split causing O'Reilly to go it alone this year without the participation,
or blessing, or issues of dealing with the MySQL camp.
I did notice the obvious use of the phrase "This inclusive, ..." in the conference description.
Perhaps they had some issues with who was to be or not be included in the conference.
"Joomla" is also simply the name of a content management system.
Using it as that is not a trademark issue.
So I would really appreciate it if you stopped spreading this "mis-information" as fact.
