Regardless of what you are waving (not waiving), the best expression is "Have you signed in?"Thank you Cagey. More specific context is that I am a teacher in a class environment and I want to ask my students whether they all have signed in while I waive/show the sign-in sheet to everyone in the class.
This sounds perfectly natural to me. It's quite common here in the US, at least in my area.I am looking for a more natural way to say the following in a class context.
- Have you signed the sign-in sheet yet?
Using the word "sign" twice troubles me a lot. It does not sound idiomatic at all.
Thanks for your help.
