send-to seems very meta, or very specific. A majority of the questions use it in a sentence of tags, or are closed. The few that are still open, I don't feel the tag improved the question. I suggest getting rid of it, or else just ridding the many questions from the tag.
Those questions are about the "Send To" action commonly seen on Windows OS when you right-click on an item.
Those that are using it as part of a sentence, they would need to be retagged.
On the whole it's a legitimate and specific tag.
