I would like to write not more than two lines at the bottom of a page, in order to thank some people, without dedicating a whole acknowledgements section of my work to that. It would be nice to draw a kind of straight line at the top of these two lines. Hence, I'm talking about a sort of footnote, which is not a proper footnote, doesn't have the purpose of a footnote and of course is not numbered. I don't even know how I could refer to such a thing, and if this is standard.
How could I do that?
