From a small discussion on How do I solve this equation involving a logarithm? there came a question should there be a tag for Lambert W function or not.
My concern, which may not be valid, is that this is only a tool for solutions rather than a topic for questions. On the other hand the same thing could probably be said about other things in mathematics which do have their own tag.
It was suggested that this would be brought to meta for discussion.
$$\textbf{Should there be a tag for the Lambert W function?}$$
Option 1: We add lambert-w tag
Option 2: We use the special-functions tag
Option 3: We do absolutely nothing (drinking beer counts as nothing)
Option 4: Anything else, which you may choose to add in the comments as a valid solution.
(P.S. Option 3 is available in conjuction with any other option)
Edit: Since it seems that this is going nowhere, I added three answers for the first three options. Please only upvote those, do not downvote. We'll give it a few days and decide.
Conclusion:
It seems that the users (Sep. 7th, 16:14 UTC. Vote count is 0 in favour, 12 against, 3 for beer), at large, disagree with the idea to have a special tag as [lambert-w]. Now comes to the other question (which may be addressed in a separate tag, at a different time) - whether or not the current tags of special functions (the special-functions but rather things like riemann-zeta) are needed, and how to decide what is the rule of thumb for starting such tag in the future.
Thanks to all the participants!
