Yes, I believe it's a SPOTD. But since it was actually a non-subscriber that
initiated it, it may be a NSSPOTD. Or NSISPOTD. Or something.
But since it's in the "Subscriber's Post of the Day" thread, I thought it was okay to use "POTD" seeing that the
Subscriber part was given (being that it's already clearly contained within the confines of the subscriber's thread). I did a little research, and it looked like other subscribers in the SPOTD thread also used "POTD" in their posts to refer to their chosen post, so I figured it was acceptable.
lain:
EDIT: It looks like POTD is currently acceptable here, as the tag under the thread title says "OK, subscribers here is your chance to pick your POTD (Post of the Day)" ...Maybe this will change. Hard to say.
