Q: One of my Tickets, on the home page, lists "Pending other collection" under Status. What does this mean?

Answer

It means that you've used the Links screen (also called Relationships screen) and set a dependency upon another ticket. It's merely a reminder that a dependency exists, but doesn't affect your ability to work on the ticket. To Resolve the ticket, you either have to remove the dependency, or Resolve the dependent Ticket first.
