Hi Deziah! Welcome. :) You can start by opening up the global chat window and joining the conversation. You might learn about some goings-on that way.
In terms of streets, take a wander over to Cebarkul in Uralia. There are often at least a few folks there. You can search your map for it, just above the top right corner of your game window.
Because we're in beta, there won't be a ton of people around everywhere, but there are still a lot of us out there! Good luck and enjoy!
Click on the Groups Link above and find some groups that interest you. there are many to choose from. Once you join one or more, you can Chat with other Group members while in the Game. Also, keep an eye of the Forums for special events such as parties and Zilloween celebrations. You will find many other players at these player created events.
Welcome to Glitch and the land of Ur. I'm always happy to say hi and chat with folks. If you like, add me to your friend's list too. The community here is so unlike those found in many other MMOs. Glitchen for the most (and I mean most) part are warm and welcoming. Take care *hugs* and Welcome again,
