I haven't found a decent, easy, freeware fond editor yet. Sourceforge has two fairly nice ones, though one of them needs a java runtime engine and the other one cygwin to work. A bit tedious if you want to carry it around with you..
The one I use is Softy, not a freeware but you do get 30 days of free use. Its website is ugly, somehow that comforts me :-) Can be found on http://users.breathe.com/l-emmett/
