@mixedmath It seems that algebra tag was emptied today. You should probably make a post on meta, so that more people are aware of this. (And also that people who disagree with this solution can voice their opinion there.)

Of course, I could make the post too; but since you made the tag-wiki and decided to try this, I consider this being your idea.

Here are the relevant edits, which removed the tag: 1 2 3 4

Thanks for the heads up @Martin

When you have a look at J.M.'s last edit here, he seemed to be unhappy about hits.

Although the reason he was upset was probably mainly the fact that (algebra) tag reappeared.

So I think it would be good if more people would be aware of this.

typo: about hits -> about this....

I've noticed that one too late to edit.
