Q. There’s a club for people who’ve worked at my office for twenty-five or more years. It is called the Twenty-Five Year Club. I am wondering why they never added a hyphen between “five” and “year” and also if it’s okay to retain the capital letters for all the words that are hyphenated. I don’t want to rock the boat around here for a club that’s been in existence longer than all of us have been in the Publications Office. We are preparing the program for their annual dinner and latest round of inductees. Should we let them retain their old name? Has this come up in other places?

Q. When I entered an incorrect password for your website, I received this message: “Invalid Log In.” Shouldn’t “log in” be “login” in this case?
