I can't seem to add tags to my own post, here:
I can't add them either at the time I posted, or afterwards. What am I missing?
I was able to add a tag to this post. I didn't try adding to your mathcad post.
When I look at my Mathcad post, the tags I wanted to add are now there, even though is gave me an error when I tried to add them. Strange. I guess don't worry about this for now. Either it never happens again, or I'll figure it out
I just added "test tag" to the post you were referencing.
Unfortunately I find no way to delete that tag - sorry for that.
It feels a bit strange to me that I can add a tag to someone elses post.
But things are different now. I noticed that I can edit a post of mine even though already somebody has replied to it and the posts date stamp doesn't change.
I don't think that that's a positive feature.
BTW, when I change something in my settings under "preferences" - "Linear Layout" and press "Save", I get an error message but it looks like the settings were accepted nonetheless.
All of my "Add tag" links are grayed out regardless of whether I created the original post, or whether it's someone elses.
