Footnotes in letters???

[Matej Cepl]

Hi,

I would like to create footnotes in letters (these are not strictly 
business letters, but rather substantial epistoles :-), but it seems to 
me, that LyX doesn't allow it although standard LaTeX class letter is 
perfectly happy with footnotes. What should I change to allow them?

                        Thanks and have a nice day

                                                Matej Cepl
