When using the modern skin, the additional links do not show up at all.
Topic on Extension talk:AddPersonalUrls/Archive 2
I created the extension for the Vector skin, I didn't test other skins. Probably the code can easily be improved to work on other skins as well. feel free to contribute.
I would like to apologize. Of course the additional links are there; don't know what went wrong yesterday. Maybe I looked at a very wrong place.
