@NajibIdrissi Maybe you could go ahead and create tag by adding it to some of the recent questions. If other users think that such tag is unsuitable, they will let you know. (It is more likely that they will notice a new tag after a post on meta is bumped.)

I just added it to a few question @MartinSleziak, but there are still many left.

Thanks!

If I notice other questions, I will add the tag.

But probably not now - as not to bump too many questions at once.

@NajibIdrissi I have copied the tag-info from SE. (Although I am not sure whether all information given there is up-to-date.)
