Welcome to LD4all ovi_mayday,
There is not really a BIG topic where we could discuss about meeting each other. There are some topics related to this subject. There were two Quests that include meeting other people: LD4all Quest #7: Spectral Moon: Join the Party and LD4all Quest #14: the Spirit of Giving. There is also a BIG Lucid Crossroads Topic. The Lucid Crossroads is a place where Lucid Dreamers can meet each other. And we also have the Who from LD4all have you dreamed about?. You can say there if you have dreamed about a fellow LD4all member ^^
Good luck with your lucid quests
