Problem: Â I don't know how to start/initiate contact with someone.
Solution:  Compliments!  If you're standing around in an area actually listen/read the conversations going on around you.  If you see someone being funny, entertaining, or otherwise engaging then send them an OOC tell and compliment them for excellent roleplay.  I've found it rare that people will ignore a compliment.  Once you've gotten their attention, then bring up the suggestion that you'd like to join in.  More often than not, you'll find people more receptive to welcoming you into whatever they're doing.  Or, if it's something you can't immediately join in on, they will usually be up for scheduling something later. Â
  Just a suggestion on how to break the ice without feeling like the Interrupting Cow.
