Where can you check to see how many of your 10 allowed devices with Match are being used?

Thanks Michael. I do know that computers count as devices and that up to 5 of your devices can be computers with iTunes Match. However, I was talking about one computer with multiple iTunes libraries in my post above. I have four iTunes libraries on my Mac (for Christmas, Christian, CDs, and Pop), all of which I had intended to enable for Match. However, after enabling my first iTunes library for Match, I then opened the next library (on the same computer) that I wanted to enable for Match, and I got a message asking if I wanted to "Add This Computer," as if the library I was about to enable was on a different computer from the first library I had just enabled. This leads me to think that each iTunes library on my computer would be considered a separate device (since computers are considered devices), even though it makes no sense. If this is the case, since my husband and daughter also use the same Apple ID and have their own computers, each with one iTunes library, 10 devices would not be enough between our computers, iPads, and iPhones.

Also, I know how to find how many devices are associated with your Apple ID at the iTunes Store. However, this does not tell you how many of those devices have been enabled for Match, which is what I am trying to find out before enabling all four libraries on my computer. I don't want to find out too late that I just used up four of my ten devices for libraries on one computer.

Thanks for your help.

But the only thing the Mange Devices list in the Store shows are the devices that you have associated with your Apple ID, right? It doesn't actually show how many of those devices have been enabled for iTunes Match, which is what I was looking for.

The only thing I see listed below Manage Devices is Hidden Purchases and iTunes Match, which only shows the date your subscription will expire and whether or not you have Auto Renew turned on. I don't see anything that mentions devices associated with iTunes Match.

I did click on the words "manage devices" and all it shows are the devices associated with my Apple ID. Only one of my devices listed has been enabled for iTunes Match thus far; however, this information is not listed. There is no mention at all of which devices have been enabled for iTunes Match.
