I think languages tag would be a very good fit here, bu t I am not sure which of the five tags to omit.

Q: What is the site etiquette about (i) asking and (ii) answering questions in a language other than English?

We have a new user who has recently both asked and answered questions in French. I think we should discuss the appropriateness of this practice.

Q: Is it ok to tag a Keyword to get attention of a specific community?

Imagine a question fitting into tags 'z' 'y' 'x' but you know a special case might be answered by a certain field of mathematics which is included in tags 'w' ,'v' and you think people often answering questions in 'w' might know an answer to the question even for more general cases. Is it ok to...

I wonder whether I am the only one who considers the description of a hypothetical questions in the above post a bit unclear.

You are not alone.

The tag homeomorphism reappeared again. It seem that it has been removed a few times in the past.

Q: If $f$ is a homeomorphism

If $f$ is a homeomorphism on $[0,1]\to[0,1]$,then I need to show existance of a sequence of polynomias $p_n(x)$ such that $p_n\to f$ uniformly on $[0,1]$ and each $p_n$ is also a homeomorphism. Thanks for help

I have removed it from the above question.

Another recently created tag is special-relativity.

Q: Problem with Kinetic Energy in Inertial Frames.

Suppose I roll a ball (without friction) down the passage and up a ramp at the end. If I release the ball with speed $v$ it acquires kinetic energy $T = (1/2) M v^2$ and, by conservation of energy. when it reaches the ramp it rises to a height $ h = T/Mg = (1/2g)(v_{initial}^2 - v_{final}^2 )$ wh...

There seems to be a consensus that it is ok to retag question after an answer is given which show that it is related to some area: Retagging after an answer is given. However, retagging it in advance in hope that an answer using methods from that area can be given is something different. — Martin Sleziak 2 hours ago

@MartinSleziak This seems to be a more recent post about tagging questions based on answers received, and that "consensus" you speak of has largely disappeared. — arjafi ♦ 2 hours ago

@arjafi The question you link is about adding possibility to add tags to answers. So it is rather different, even though one of the answers is certainly related. However, this is only a side issue to the current question - as I said in my comment, retagging after an answer from some area is certainly different from adding tag in advance. — Martin Sleziak 1 hour ago

The two questions mentioned in the above comments are:

Q: Retagging after an answer is given

Sometimes a question is asked under a perfectly suitable tag, but is given an answer which is addresses respects strongly related to other tags. What should be the proper etiquette regarding retagging the question? Obviously when there are many answers addressing the question within the confin...

Q: About extending the tag system to answers, too

Recently, I gave a solution to a complex analysis problem that avoided the standard complex analytic tools, but relied on a property of the modified Bessel function of the first kind. I bet this happens quite often: someone proposes a question, tagging it accordingly to the area of mathematics i...
