2 Gomunguls. There's nothing wrong with forum members meeting. If a person frequents our forum and plays — then it means they're interested. If they're interested, it's natural to communicate with people in real life, at tournaments and meetups.
Although, I too separate people I know in real life from people on forums.
When I talk to an acquaintance via ICQ or PM, I picture a familiar person in my mind, which is convenient for natural conversation.
But with a virtual acquaintance — you tend to respond more often with standard replies, involuntarily.
