Yeah!!!!! Great news!
I leave mine in all the time - only take them out weekly for a dip in the ultrasonic! If you do keep them in, just be careful because very occasionally the screws loosen slightly so just check periodically that they're not working loose.
By the way, I think the posts on the screw backs are larger than "normal" posts which is why you had a little trouble getting them in. I have exactly the same problem.
