I heard in a on line lecture the claim [made with a straight face and not during a Purim Seuda] that Rav Menashe "HaKotton" Klein ztz"l had a woman editing his tshuvos that were published in his Mishne Halachos. The speaker heard it from someone and believed him. This explains the beautiful modern Hebrew in which the tshuvos were written. [Which by the way is false. The tshuvos are written in beautiful Hungarian Rabbinic Hebrew. A different dialect than the modern parlance].
Now I can't prove this claim is false but I am comfortable saying that this is only slightly less likely than a female graduate of Matan ["I heard a gevaldike derher in the Ketzoit from Morati Virabati Malka Shlita"] giving a shiur klali in the Mir Yeshiva after which she would serve as Shaliach [Shlicha?] Tzibbur for Mincha.
This might however happen when Simon and Schuster buy rights to the sfarim and reprint them ["edited by Rabbi Amy Wokestein"].
