this may sound dumb, but what is an Ipo? and how can I use it in a game? If you fell like answering a stupid persons question, feel free to leave a reply. 
thanks
I dont know 100% how ipos work, but I use a part of them and I can explain it to u, with it u can explain more
make a plane, on frame 1 it has normal scale (for example) and on frame 2 it has double scale
now make an logic like that:
Mouse Over
And Controller
Ipo , Flipper from frame 1 to frame 2
this means everytime ur mouse is over the plane, it will double its size if ur mouse is not over ur plane , it will return to normal
with this u can expiriment more with ipo settings and u can understand more of how it works
I’m sorry, I’m not an ipo expert but hope I helped u ;D
sorry I double posted the same thing, i dont know how to delete posts so I edited it!
OK, yes that was helpful. just curious…Can you add an ipo for a single user?
OK, ipo’s are like macros
they are recorded actions.
Ipo can affect many different properties, such as scale, color and location, rotation…
in game you can play back these actions.
you…completely lost me, but I think I know what they are. YouTube. a beacon of light for noobs like me
