Response to T-MAX developer concentrate - shelf life after opening

It's been a while since I used T-Max developer, but I seem to recall keeping an opened bottle for quite some time and never experiencing any problems with it. Kodak's documentation says: "You can store working-strength solution in a full, tightly closed bottle for six months, in a half-filled bottle for two months, or in a covered tank for one month. You can store the concentrate for up to two years." The two year figure is probably for an unopened bottle. If you plan to store the concentrate for any great length of time, I would suggest you obtain several small brown glass bottles and put it in those, with as little air as possible. That should give you maximum shelf life. If your current half-full bottle is only two months old, it should be fine, and if you use the rest in another two months it's not likely you will have any problems with it deteriorating before it is all gone.
