I have a dispute with an acquaintance over this sentence:
If [you're] looking for aliases that will be displayed in the help message, see the link above.
("you're" is omitted)
I'm pretty sure this sentence is incorrect because the conditional clause has its pronoun omitted, and I couldn't find any rule such an omission would be justified by. I believe "you're" cannot be omitted without rephrasing the sentence.
My acquaintance argued this omission is acceptable in technical documentation and often used as a sort of "shortcut". He wasn't able to provide any links to dictionaries that would support his claim, I never saw such use described as acceptable, and I am not convinced by his word alone.
Who's right?
