I get the newsletter from the guys who fix the bugs, not that I can understand a lot of what they talk about, I some how signed up for it when I first started going there :lol:
There is an Inkscape forum
here you can discuss things and ask questions like any other forum, might see you over there some time :D
To report a bug you click on the in the Help menu, then you have to scroll about, read everything and work your way through to the bug reports, it is easier to look and see for your self than me try to explain it all. I've got used to it now, but at first it was a bit scary :o
