Currently, clicking "thank" on a diff or history page shows something like this:
Change this to
with "Help" by default linking to mw:Special:MyLanguage/Help:Notifications/Thanks (and modifiable much like these).
Rationale
This request was prompted by this discussion at enwp, in which the OP said:
It wasn't clear to me whether my thanks had been sent already and if it was asking me if I wanted to publicly thank the editor on top of that, or if publicly thanking was the only way to go.
Which is precisely the same concern/confusion that the OP of T159302, which resulted in changing the confirmation message from "Send public thanks?" to "Publicly send thanks?", had:
The message "Send public thanks for this edit?" is confusing. People have been known to misinterpret it it as giving the user a choice of "Send public thanks" vs. "Send private thanks". Actually the choice is "Send public thanks" vs. "Don't send thanks".
So the rephrasing has hardly helped.
The word "public(ly)" has been nothing but a source of confusion. I understand it was added out of concern for the feature being construed as something private (T90486), but it's steered people too far in the other direction. Pdebee said in the aforementioned thread:
A few years ago, a new joiner wanted to thank me for my initial help with her first steps as an editor, but changed her mind because she thought that “publicly” meant that tens of millions of other registered editors were going to see what she’d hoped would be a simple, private signal of personal appreciation.
...when in fact only who thanked whom when, not even for which edit or on which page, is visible—and only on Special:Log, not on any diff or history page or anyone's watchlist.
The addition of a help button and the removal of the word will hopefully put an end to this long-lasting confusion, which is why I'm submitting this as a single task.
