This is a useful site for keeping track of your completionist and trimmed completionist requirements:
http://www.maxcape.com/ (http://www.maxcape.com/)
It keeps track of everything, more specifically than the cape rack itself. For example, on my profile here:
http://www.maxcape.com/profile/Emeris6 (http://www.maxcape.com/profile/Emeris6)
It shows that I have 300/401 Mobilising Armies rank, 73/4150 Castle Wars tickets, etc., instead of just saying that the requirement is incomplete.
Note that this is manual on everything except for skill tracking.
The site also has a few other useful features, such as designing your own cape colors here:
http://www.maxcape.com/designer/ (http://www.maxcape.com/designer/)
Where you can also display, view, and vote on other capes submitted.
I hope that others find this as useful as I have.
