In an email I received from my university, the following is stated:
Should you have decided to do the assignment, please send us an email.
My question is whether the inversion and usage of should is right here. To me, "If" instead of "should" would make more sense. In my research I've only found present tenses of the "should-inversion."
I understand the usage of "should" in this case is highly formal, yet the rest of the e-mail is very informal. The more I look at it, the more it seems normal to me.
