Welcome back from Wikimania 2015!
Wikimania 2015 was the first Wikimedia event that I attended and it was such a "great" event. I learned so much things about most of the Wiki projects and had to chance to share my knowledge -which are, I can cleary say after the event, not so much- with other contributers. Attending to Hackhaton sessions was not my intention at the first place, but after being there i chose to attend. I learned so many things during these sessions. I met with the founder of the idea of The Wikipedia Library, and took so much information about the project. I was the one who attempted to create that project on Turkish Wikipedia.
About the organizastion, there was nothing wrong or missing, it was just great. I had a great experience in the event and I hope I'll attend the future events, too.
