I am a longtime, satisfied user with Personal Pro account, which has always been exactly what I needed. However, for an upcoming event, I need to be able to provide a number of people with Uploader/Viewer access, but only for 24 hours. I will likely never need to provide that level of access again again. Is there any way to upgrade for a very limited time, then return to my Personal Pro account? I don't want to pay for something I won't use again.
Thanks.
