Fast Track Visa Application--Timing question.

Hi all:
For those of you who utilized this online option AND then applied in person--how far in advance did you fill out the online information?  Can't really tell from the site how far before one is planning on going to the consulate one SHOULD or CAN complete the application.
Thanks for your input!

Ginger,

I may be incorrect on this but when I went to the Brit Consulate in NY earlier this week, there were several people that went the fast track route but those that were discussing it said they could only complete the fast track applications on the PCs provided at the consulate...not from your own pc at home.  This makes no sense at all to me (and so really may not be correct), but that's what was being discussed at the consulate by those fast trackers.
