Is there a way to delete terminated games because they always show at the top of my game list. Or is there a way to sort them where open games and active games are sorted at the top but terminated games are not.

I'm not sure where you are seeing this. It is under the "My Games" heading? If so you have a meny choice high up on the screen that says "View". If you go in there and select "Live" you will only get active games, ongoing and those that hasn't filled up yet. Not terminated ones nor finished ones.

You can also press the "Status" column heading to sort everything the other way. With Terminated on top I'm guessing you have an alphabetical sort from Z to A.

I myself have games sorted by "created" to get the most recently created ones first but that's just a matter of taste. 

Okay thanks, that worked.  I didn't realize live games included ones not yet started. Thank you.
