I'm slowly coming back to myst online. What's everybody running? I'm seeing OpenUru, Gehn Shard, stuff like that. I recently logged into the main game and not many people were one it.
I'd also like to know what people are using for age creation nowadays?
At the moment, I'm guessing we're experiencing the summer slowdown. When it's nice out, people usually head out to do things instead of congregating in the cavern. I predict things will get a bit busier as the weather gets colder again. 
Thanks to open source, there's a variety of shards to choose from, although, despite the lack of activity there when you last visited, the MOULa shard still has the most explorers currently.
As for Age creation, I'm not entirely sure what we can and can't mention here, so I will also direct you over to the Guild of Writers site for more info. I can mention that Cyan's preferred method (although they have yet to release any fan content) is to use 3DS Max 7 with their plugin to properly make compatible content.
In any case, welcome back!
