What to expect from uncarbonated keg sitting in fridge

I have an uncarbonated keg of beer sitting in my fridge that has been there for 3 months.  Basically, I got through brewing, tried kegging for the first time, had difficulty with the co2 regulator and then had just a bunch of stuff pile on that messing with it got pushed to the back of the line and its still sitting there in the fridge.  So, it never got carbonated.  I wanted to go ahead and fix the CO2 setup and tap it, but wanted to find out if the beer should still be ok or if there is anything I should watch out for?

Exactly...  Carbonate it to how you like it and give it a try...  Depending on what it is, it might be better than when you left it there.

Thanks for the reply, I'll get to that this weekend and let you know how it goes.
