This may be a naive question, but why are some users manually retagging all the questions?
I don't want to discuss if it's necessary or not. Let's assume it is.
But all the questions must be in a database. It's a matter of a (maybe not simple) query to remove the grammar tag.
Of course, when it is done manually, one can add some new tags which are more appriopriate. But what is the point in doing that for questions which were active a year ago.
I'd propose the follwing alogorithm:
For all the questions which are older that 2 months (this value can be changed) remove the grammar tag.
If a question has no tags (the grammar tag was the only one), manually add some tags.
- Manually remove the grammar tag for the rest of the questions (this is optional, we could deal with all questions in the first two bullet points).
I'm sorry if it's a dumb question, but automating this process would save a lot of time. Why can't be it (or isn't it being) done?
Edit: I didn't mean to ofend you, M.A.R., or anyone else, or undermine your work. I didn't say you have to do as I suggested, but I asked why you haven't been doing in that way.
It seems normal to me that when I see something I don't understand, I try to figure it out on my own and if I fail, I ask people who have much more expertise and experience than me. It doesn't matter whether it's a solution on a website or a detector of an unusual shape or a suprising solution in a data aqusition system. I can always learn something from that.
So I am sorry if I somehow offended you - I did not mean that.
