Advice needed: I'm a little afraid of my GeeeTech A20M's print bed

[simbokarl]

I've only printed the test model. It performed admirably, perhaps a bit too well. It literally took a hammer and a putty knife to get the print off the bed. Is there a way to make it a little bit easier. I need to print some relatively thin, flat flags. How can I make it easier to pull the print off the bed.

On a separate note, how can I tighten down the bed? It wobbles on the left and right side. Front and back is good, but left and right is wobbly.10.0.0.0.1 192.168.1.254
