[zware]

Xavier: It's been long enough that I don't remember whether regular Users can adjust Dependencies, but since you didn't do it yourself I assume they can't. I've just given you the Developer role, so you can now :)

[xdegaye]

No, regular users can't adjust dependencies, but I can now. Thanks Zachary.
