Ok I have to say I'm confused here, the only way to publish from any GPSr to GC.com is through the field note feature, that is a GC.com limitation not any manufactures. So your saying you want to publish a field note without making a field note?
Making a field note (atleast on an x10 series) is automatic, when you are looking for a cache and find it open the Menu and choose FOUND IT. If you choose not to edit the field note it will put one there for you that has the "TIme to find" and says Found, you can edit it after you upload it to GC.com before you post it. Maybe your canceling the navigation, reopening the caches page and then manually changing the status to found, this is the long way to do it and would skip the auto note creation.
Create field notes on the explorist GC when you find the caches, then connect to GC.com when you get home to download your field notes straight to GC.com.
You can not create a field note on Vantage Point, you have to make a field note in the field on your GPSr, then download them to VP or GC.com!
Don't bother with Vantage Point at all.
