ing like this and I admit its largely a semantic difference but forums are generally centered around a theme, in this case obviously chip music. "General Discussion" implies general discussion about said theme and off topic implies discussion about anything other than that theme.
It seems that it isn't the case, General Discusion IS off-topic, but without the completely uselesss silly shit.
Like, "here you can talk about other cool things", which is why I thought threads like the photography one should be there.
