It was only 10 hrs ago, be patient... :)

Commercial use or the data and map tiles in their unmodified forms is
allowed as long as you provide the required attribution... Anyone can use
the data, which is the entire point of having an Open streetmap :)
If you were to modify the data or tiles and then publish the results of
those modifications I believe it can get more complex, so you'd need to
check the license and perhaps discuss the issue on the legal-talk list if
you needed to do that...

If you are only looking to provide a slippy map view, and not use the data
directly, you should check this page too which is specifically about using
the tiles produced by the mapnik based tile server run by/for the project...


The key bits that would be potentially relevant in your situation are
1) that you shouldn't bulk download tiles, i.e. don't download all the tiles
in an area to host directly on your own server
2) the point on heavy users, which might not be an issue now, but, if your
site is, or becomes, busy then you should look into either setting up your
own local tile rendering instance, or, look at commercial providers of
rendered tiles such that you are not overloading the project public tile
