Okay... I've made some changes. wp-register.php no longer tries to email you your password -- it's just displayed right there. I couldn't do this with an action hook without making things totally ugly, so I've just modified the file directly. Hopefully Sourceforge will sort out their spam problems sometime and then we can put it back.
Everyone who has registered an account previously should have been emailed a password by me. If you haven't got yours, please email me again.
In other news, for those who are using the Inkscape website locally: I deleted wp-config.php from CVS. This file is different depending on each user, and we don't want anyone accidentally committing their passwords to CVS. A template of the file is found in wp-config-sample.php -- just copy that over and make the necessary changes.
