Improve the wording of the availability invite

This, for example, is not grammatical: "Would any of these times work for you for a 30 minutes meeting? (CST)"

It should read "30 minute" meeting. That's proper English.

Also "would any of these times work" is not quite right when you offer a block of say 2 hours because none of the times listed will be 30 minutes. It should be more clear and say something like "time windows" or "time periods".

I suggest two things:

1. Fix the default to have more clarity.

2. Let me edit the default text. I would much prefer to just write it in my own words, which is what I do now by manually editing.
