I am at the moment pretty happy about how i interact with my friends. I have booth rl and internet friends but i keep contact with most of them over the internet.
But i guess one of the best solutions if i need to get this stressful amount of people (more than 2) on one place would be like a house in a forest on a cloudy, not rainy day.
And that house has a fiber internet connection and a room with pcs for all.
If the pcs are from like 2005 and only have warcraft most would be fine with it but like only most.
