I am new to this game and I was wondering, is there a place where I can look up a player and find them?

In the top right on the BK page (tan area), you can see a link called "Search" (http://beastkeeper.com/search)

Just select "Search for Users" (Same way you would for pets).

There is also an "online users" list: http://beastkeeper.com/online This can be found at the bottom of the page. :)

I hope that helped!
