Results of skin tests on SVN head, but expected 1.17 will be all but the same:
Chick - Fine
Classic (Standard) - Sidebar below content
Cologne Blue - Sidebar below content
Modern - Fine
Monobook - Fine
MySkin - Sidebar below content, but is also like that on 1.16wmf4 http://en.wikipedia.org/wiki/Main_Page?useskin=myskin
Nostalgia - Fine
Simple - Fine
Vector - Fine
So for me, 2, possibly 3 skins with the same issues, that need looking at for 1.17
Version: 1.17.x
Severity: major
