Obviously, you need to crack down on the tenant removing the safety devices (what is their reasoning for doing so in the first place?).

@Frinee WarrenTypically if the sill is below a specific height you need to use tempered glass and limit the window to opening to no more than 4”I believe it’s 24” but could be wrong on thatWe have a window in our son’s room that is too low so it has tempered glass and limiter device

While hardcopy isn't going away anytime soon and has some advantages (no batteries, cheap, loanable, free at the library, doesn't cost a mint if you get it wet or lose it, etc), The Kindle and the iPad and the e-books available on such devices will continue to gain ground I think.Having the ability to download any book you want in seconds over the cell network, as well as carry your entire library with you at all times, plus search it and bookmark it, have it read to you when driving, and be able to take notes and look up words in the dictionary, etc....that's pretty neat too, and it keeps getting better.I'll look forward to the ebook, Rich!

I don't typically use bookmarks because I use too many different devices.

There are 1-page templates out there for this if you want to write it down, or use your mobile device.

Fast enough to stream 3 devices.

I am viewing the thread on an iOS device, on the Apple app.

Turn off all devices and read. 

It's all on a googledoc so that I can access this template from any device I happen to have.
