I believe the story with Rita and the bug-zapper was a Harmonious one, Bobmin's "The Power of the Press" where dear Rita gets too close to one at the Granger residence and ends up quite incapacitated as a result.
Yeah, that was an interesting story by Clell and quite amusing, especially with the changes, not necessarily connected with the technologies shown, that Harry went through. 'Twas especially amusing to see Ginny talk herself out of Harry's affections.

Heya Cat!
Power of The Press is one story where the Zappers made an appearance, but not the one I'm talking about, but neither, nor there.
Yeah, All of Clell's stories are terrific. If I'm not mistaken, Ginny was so appalled at the idea of 'doing that' and Hermione was saying 'Let's do it! Let's do it again!"
