Is it possible to overwater a mounted orchid?

Thanks Gary,

Yes, I'm starting to find out what it needs and I'm getting less worried about killing it with every day.

This one is on cork with moss underneath the plant. It's a thinly rooted Miltonia. In my enviroment it seems to need twice daily watering, once a day for too many days and it shows signs of shrivling, it plumps up again with a good soak followed by twice a day watering.

I really am starting to enjoy growig this one.
