Steam Trade Policy Update

For those of you who do not know the policy originally stated it's 7 days after mobile auth is added to the account that you are able to trade.

This is no longer the case, it is now 15 days. Removing mobile auth also resets Steam Guard and you have to wait 15 days to use Market again as well.
