@Pat Where I live, "thumb tacks" are called "drawing pins" - pinning is natural in English English
I didn't know that. Thank you.
Now it makes sense. I guess the folks who chose that icon probably didn't know about the North American term "thumb tack" for that device.
I guess now I'll have to find another toot to pin in my profile...
In the US we use the terms "pinning" and "put a pin in it" to refer to remembering something. And when something is fastened using a thumb tack we usually say that it is "pinned" not "tacked", although the latter is sometimes used.
@Pat Sure I have. But a thumbtack can pin just as well! And less annoying to handle too!
