Why can't I join a mock draft?

I'm getting the same message.

Yahoo answers is having server problems tonight. Perhaps the mock drafts are as well.

there are a lot of people trying to use it so wait until the top group of draft waiting rooms are at a minute then scroll down to the bottom of the page and right when the top group of drafts expire, refresh the page and there should be a number of slots open at the bottom. Don't click on the yellow button that puts you into a random group. It is quicker and easier to just join the group directly. A new group of drafts appears about every 15 minutes. Hope this helps.........

Skip Yahoo and join www.mockdraftcentral.com you sign up for free and participate in one mock per day and they use Yahoo format for leagues. You can also choose your position and some different choices for scoring types. If you use the pay version you can setup just about any configuration you want. It's a great service and you can get a mock every 15 minutes.
