Is social expat life existing in Poznan?

Hello,
I am originally form Poland but have not lived there since i finished high school.
so - now after 12 years of my abroad adventures i am planning to move to poland,...and poznan will be an option.
...but i am concerned about social life part :) :)

I do not see Poznan on Internations - and also while googling i do not see any kinds of meetups for expats being organized in Poznan.

What is your experience in getting social life started in Poznan?

thanks for feedback!
