I would have preferred github over sourceforge, the quality of sf is poor these days, it is a faint copy of its better days, it has so many advertising, tracking and even add-on-downloads. Too commercial for my taste.
For collaborating, github is so much nicer.
If you want to use github, why not put it up there then. I doubt this is going to be a hotbed of activity that it can't be ported. I don't used Mads either, so I'll just stick with my Mac/65 copy of the code.
