Do you have any tips on changing the LobbyID for the chat room from an Int datatype to a Guid.  I've already tried changing the column in the table to a guid, but of course the code does not support this.  I tried to change all the places where it is set to an int for LobbyId.  Yet, no luck.  I'm sure that it is possible.  My biggest problem is that i'm not that familiar with c#, only vb.  Any tip would be appreciated!
