A tinsy winsy question

I've been reading the transcript of an old webchat with JKR, and a 
certain part caught my eye:

"Q:You have such a phenomenal imagination! Is it a result of a very 
imaginative childhood?
A:First of all, I will be using your name in a future book..."

[Barnes&Noble.com - September 8, 1999]

Link to the transcript I've read from:

barnesnoble-staff.htm

Does anyone know what name they are talking about? 
(Because I'm dead curious)

recommending everyone to revisit the old transcripts.
