to a) I am well aware of it Cairn. I don't have /greet in my shortcuts anymore, and didn't really like it to begin with. Most people do a greet&run how it is called or they run past me so quickly that I can't even press enter.
I do tend not to start a RP with a random person passing by. There is also that problem that those busy grinding (It used to be only the smiths, not sure if those grinding herbalism or leatherworking are the same) didn't reply even though I RPed some stuff right in front of them.
And the possibly person standing around doing nothing is in the most times afk... Maybe it is just my luck.
to b) Cliques is another thing. You have to be part of one. It is the same with guilds. My chars always had been in guilds after they were popular like DE, Outlaws, Cult of the Wheel (forgot it's previous name

), Ad Lib (when it was still small) to name a few of them. Don't understand me wrong, I joined those guilds for some IC reason. But still I always had to rely on friends outside of those guilds to RP. And most of the people I used to RP with have vanished over the time.
to c) The RCD is a nice place to meet, if there were people coming when it opens. It used to run well in the beginning of the year after the masquerade ball event. But then no one showed up anymore and so I stopped opening it, since it was a waste of time.
Social events would be nice, but there has to be someone to run it.
