[Inkscape-devel] How to propose patches

I created a patch to improve the selection toolbar. It creates two new pull-downs. One determines whether the "X" coordinate refers to the left of the selection (as normal), or the center, or the right; and whether changing the width keeps the left, center, or right edge in place. The second does the analogous function for "Y".

Several years ago, I had write access to the inkscape archives, but no more. Can someone please explain where I should send a patch, or if there is some other procedure?

Thanks!
