@MartinSleziak As tested in another room, once I click on "cancel stars", the system does not allow me to star the same message again.

@user21820 The question When is $MM^T$ invertible? - revisions/timeline which you mentioned above was reopened and then closed as a duplicate. I cast the first duplicate close vote after this comment from the OP.

@MartinSleziak I don't think a user can star/unstar his/her own message, and if the issue has been dealt with I don't personally care whether it is still starred after unpinning. =)

Yes, you can star and unstar message.

@amWhy I land on the delete side, because there isn't even a clear question anywhere I can see. =)

Anyway my question was: The stars should be completely removed, not just unpinned when the issue is settled?

The possibility 2) I mentioned above.

I was not sure mainly because I saw your message which said "unpinning now" but the star remained there. (I removed the star just a few minutes ago - after you said "I don't personally care whether it is still starred after unpinning".)

Anyway, I have to do a few errands now, so I'll be away from computer for a bit. If the above messages clogged up the room too much and they are off-topic here and you want to move them elsewhere, plese move them into my room rather than into the trash.

I personally don't care whether to leave them pinned after done, so others can do whatever they see fit. Okay I'll move CRUDE-unrelated comments into your room. Sorry I also had to leave my computer for a while just now. Thanks! =)

@SimplyBeautifulArt The post is now closed and deleted - revisions/timeline. So I unpinned and unstarred your message.

This nonsense post says that x^(1/2) = ±sqrt(x)... Please help to delete.

This post is hardly an answer and was recommended for deletion by review at 6 to 2. It really has no value, don't you think?

@user21820 Up for deletion again; has minus 1 score, and currently has one delete vote :)

@amWhy Thanks for the downvote! But the delete vote is mine it seems.

@user21820 No mine. The post was at "0", I downvoted; I refreshed; saw delete (no votes), and voted to delete. You can redelete (not like a vote to close, which after reopening, no previous voters to close, can vote to close again.) Oops, I guess my first attempt to vote do delete didn't "take"; it now also has my vote, with your vote, with only one more vote to delete needed. @SimplyBeautifulArt ?

@user21820 Only one more delete vote needed there, now, too.

@MetaEd: Hi! I've noticed you in this room quite a few times. Would you like helping us out with closure/deletion? =)

@user21820 I am only carrying 101 rep at the moment -- I mod over at EL&U.

@user21820, @SimplyBeautifulArt, @Did, etc, this problem statement question needs to be closed. math.stackexchange.com/questions/2393601/…

[ SmokeDetector | MS ] Link at end of answer: Good book for self-learning sequence and series by Richard on math.SE

Problem statement question (@SimplyBeautifulArt, @user21820, @Did, et al.) Needs two more votes to close.

Sorry, all (@SimplyBeautifulArt, @user21820, @Did, I failed to actually include the link, (dah!!!) again: here it is math.stackexchange.com/questions/2393644/…

@amWhy This one was self-deleted.

@SimplyBeautifulArt Yes, indeed, I saw that.

@amWhy Available for deletion

@amWhy Hm, I guess I happened to answer some PSQ's... my bad

→ 1 message moved to trash

@amWhy And I've removed my comments, if you care to remove the last one

@SimplyBeautifulArt Done.

@SimplyBeautifulArt I get it ... when the topic is something you know and love dearly to share, I get it; I'm the same way with many logic questions.

@amWhy I guess yeah.
