TIP: Title rasterized type layers

If you rasterize a type layer you not only lose the ability to edit the type, you also can't tell what font and size it was. So, before you rasterize the type layer, make note of all the settings, and then name the type layer "Garamond 36 Bold centered" (or whatever yours is).
That way if you need to create some more type in the same size, you'll know where to start.
