How to clean up (remove) packages on Igor Exchange?

I recall asking or reading an answer, but I do not remember and cannot find the answer.

Much as with crepe myrtles in the southern USA as we move from the winter to the spring, I would like to cull through my slew of packages that are posted on IgorExchange and remove those that are serving now only as clutter.

Is it possible to grant folks such as me high enough privileges to do this on their own?

Sorry, that's not possible. We generally don't delete content that isn't spam or obviously a mistake because someone else might be relying on it, improbable as it may seem.
