Model sentences might not be ideal for this page. I think it'd probably be better to list a few examples in the usage page, showing the before->after so it's easier to see the transition (sentences can't be 'paired' in the model sentences tab).
Can you help think of the different times that this can be used?
(prohibition) てはいけない > ちゃいけない (or だめ in place of いけない) ではいけない >じゃいけない (or だめ in place of いけない)
ではない > じゃない

A few examples works fine too. What I meant to ask was if there was going to be something other than user sentences to look at for this one. I'm not too familiar with this grammar point so I kind of had to stare at it for a bit before it clicked ^^;;
