Any existing internal links on posts need to be converted to show https vs http, your forum install links should also be updated so that any references to on site links and images are linked to the ssl version otherwise users will be prompted that data could not be completed due to it being an insecure local resource.
Some instances in the UBB hardcode http into links, such as user avatars, so will have to update those manually as you come across them (7.6.0 has these updated). Any images linked to as well will need to be using https otherwise you'll never get that "green shield" (note, the color of the validated SSL notification in the browser is specific to that browser, they're not all the same).
You'd likely want to also force ssl via the webserver, so that users are forced to use SSL (which will give you the bonus search engine ranking that i'm sure you're after).
