There is a bug on the wiki causing for new source junk to appear on the Wiki! It makes all ' appear like & a p o s ; (without spaces). For the meantime, DO NOT EDIT IN VISUAL. Source is immune to this, so just settle with Source. I repeat, SOURCE ONLY. I am not the cause of the bug, it was introduced earlier today during an HTML Update.
It may clear up after a while, so keep posted!
