Kludge indeed; and it is entirely unnecessary: Wei Dai's script already makes it easy to search a user's comment history.
I again urge those responsible to restore the prior appearance of the site (they can do what they want to the non-visible internals).
Wei Dai's tools are poorly documented, may not exist in the near future, and are virtually unknown to non-users.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
