Re: Query regarding temporarily-uploaded files

Thanks Jim and Anthony. Jim, You are right, your solution is doable. But one thing I am a little skeptical about, is what would be the percentage of the people willing to suggest a new name "immediately", versus the percentage of people who would like to cancel the current upload, and come back "later" after walking and coming up with a new name. Anyhow, let me sleep over it :) Anthony, your solution is really a special case of Jim's solution :) Thanks guys for the quick replies; I am obliged, really.
