From a MileNet email:

Rather than continue to provide such inconsistent service, we'll be shutting down indefinitely and return if and when we have the resources we need.

To redeem the miles you have earned on MileNet, please go to http://www.milenet.com/redeem.htm and redeem your miles ON OR BEFORE MIDNIGHT (Pacific Standard time) on FEBRUARY 27, 1999. There you'll be able to redeem the miles you've accrued. ***After February 27, you will no
longer be able to redeem miles.***

Please keep the following in mind when you redeem your miles:

-Be ABSOLUTELY certain that the account number you enter for redemption is your
AIRLINE PROGRAM ACCOUNT NUMBER. For American this is a 7-character string of letters and numbers. For Delta, this is a 10-digit number. If your number is incorrect, we cannot credit miles to your frequent-flier account.

- We've lowered the minimum redemption to 1 mile, and if you had less than that you'll find your account has been bumped up to 1 mile.

- You can only redeem the integer portion of your mileage amount. For example, if you have 3.2 miles, you can redeem 3 miles.

- If you had not previously selected an airline, your account has automatically been set to American. If you had previously chosen Delta, you can redeem your miles on Delta in full. (Low inventory of Delta miles
prohibits us from accepting any more Delta accounts).

Well, now I guess I can claim that 0.00000001 of a mile racked up on the counter, gee, they'll even give me a whole mile for my troubles. (Actually I did get 125 miles from them so far, from a referal and a bonus for all the problems.)
