Well, using hook fetch_userinfo you'd want to use $user instead of $userinfo. You could try that, since it should be pretty quick to make that change, but looking at showthread.php I think I may have been wrong. Sorry about that, but it looks like showthread.php gets the userinfo as part of the query for posts in a thread, so I guess it doesn't call fetch_userinfo(). So it doesn't look like you can do much better than doing it in postbit_complete and using $post in place of $userinfo (although you should otherwise be able to use the same code, of course). And if you want to cache it, you'll have to build your own (just save arrays with lrank and srank in a global array with userid as index, and check that before executing your code). But you're not doing a db query or anything to get your answer, so if it were me I probably wouldn't bother.
