[Remiechi]

I prefer the more subtle approach - I advised my daughter to send out thank you notes to her rec writers about two weeks before recruitment began, so in case they'd forgotten about it they still had time to send it in.
For my submitted recs, I've received an acknowledgement postcard from the chapter for every rec I wrote within a week after rush, with the exception of the one I wrote for my own in-house legacy daughter, who pledged elsewhere.
