I've actually done some thinking on how to adapt the favorite forums hack to do just this.

If it were set up in the same manner, where someone had to click a link to a "myTopics" page, it wouldn't be that great a strain on the database.

If I'm thinking this correctly, all you would need is a 2 column table to store a userid and threadid. The actual descriptions for the page could be pulled from the thread table that already exists.

The thing I would what to add, though, that might be a little tricky to code, would be that when a person started a topic it was automatically added to the list.

Also, instead of using a checkbox on the list like the Fave Forums hack does, I would prefer to have a link inside the topic that could be clicked on to add it, and if it was already on your your list, to remove it. The check to determine whether the topic was already on a user's list and place the approproate link might add a little time to rendering, though.
