It's possible, it just depends really on how you want to go about it.

The easiest way (from a coding & management perspective) is to have a selection of profile fields in the usercp that the user can add the URL's to their favorite forums to. For naming reasons, this would need double the amount of fields to the most forums that you would allow, so it would be a long list and take a while to set up correctly.

From a user perspective, a nice "add me to favorites" button in each forum would be ideal, but this would be much more difficult to code.

Finally, a possible (just thinking about it not looking at the coding side of things) solution would be to work with the subscribed forums in generating the dropdown. The practicality of this is unknown though, as I have no idea how much work would be required to get it working.
