Shashi Tharoor's wife's body found in after affair allegations

This was link on the main page.  The article itself is headlined "Body of Indian minister’s wife found in New Delhi hotel room after affair allegations".  Sloppy editing (which still had not been corrected after being up all day).

This mansion in is Mississauga

This doesn't much make sense to me! 

Prosthelytize?

Is the "prosthelytize" an accepted variation of the word proselytize (or proselytise, in British English)?

I don't think so.  It's probably more than a typo, but not in common enough usage to be an accepted variation.  My guess is that many people are unwittingly substituting the familiar (and easier to pronounce) "prosth-" prefix (as in "prosthetic" or "prosthesis"), not realizing it denotes "adding on", as opposed to anything having to do with encouraging religious conversion.
