Mod – I had clearly indicated what I had used the abbreviation for (yesterday) before Toi’s reply (6 hours ago) so assumed he must have had a problem with the phrase. Anyhow, I am unaware of another use for the abbreviation (at least here in the UK).
I don’t know which mod deleted your comment, but I don’t see what they (or Toi) found objectionable, so I’m going to put it back up.
