I agree - avoid tape on the inside. I've seen it fall down and can only imagine the horrible consequences. I put the tape on the top outside of the screen - the snake can not come in contact with it.
And I also have to agree that I have never seen any hostility on this forum - unlike many others. When I meet people on some of the other forums I go to I always recommend that they join this on and tell them they'll find nothing but a nice group of people very willing to help anyone out. It's such a relief to have a 'hostility free' forum to go to.
