Feel free to host your own girls-only event.
As well, you're most welcome to advertise Eurofurence among potential female attendees.
Con Staff, while of cource positive of having more females attend, is busy enough to make the fully booked con run smoothly, rather than pondering how to change the furry fandom to have more womenfolk interested in it.
The Ladies-only day in the Sauna however did not work out as intended, and will not be repeated, as far as i'm informed.
