Hi,
####instagram
there is no instragram account. Feel free to go for it.
####twitter
There is a global twitter account. I can’t share the account as it is meant for global messages only. But the account retweets a lot of the local twitter accounts. So post a tweet with #OSCEdays and it will probably gain more visibility through that account.
We can create one for OSCEdays Berlin. But growing a followerbase on twitter takes time. And if it is for marketing purposes only the impact is rather small. The OSCEdays global account as almost 1000 followers. And it creates less then 5 clicks of traffic per post. So it is a lot of work. But if you are up for it, go for it.
Use your email address for it for now if you set one up.
Here is the Berlin Facebook GROUP - as posted already by Julia (I make you too also admins there)
And here is the Facebook EVENT for June 2016.
Jepp, an event grows a followerbase quickly. But everything is lost 1 month after. A page creates faster a followerbase. But it is about one-way-communication. The OSCEdays is not about one way communication. But the group was growing very slow. And not much posting (other than from me) was going so far.
