Hello,
I'm glad to announce that we found a date for the LibreOffice admin weekend, which is now scheduled from
Friday, July 18 to Sunday, July 20
A location is still to be determined. Given most contributors so far live in southern Germany, it's probably most economical to host it in that area, but that's not set in stone yet, depending who else is interested to join.
That being said, I'd like to emphasize that the admin weekend is not only for existing infra contributors, but also for interested volunteers who'd like to join. Location, agenda, wiki page and further details will be announced in time on the website list.
Looking forward to hacking with you! 
Florian
