Appriciation messages has become very important now:
Appreciation messages have become very important now, in view of reduced numbers from members. Though we may look more professional in this way, but a lot of appreciation is also required from members for posting detailed and wonderful images and for posting many new additions etc.
I thank … for being proactive in this matter.

Yes … This is in a way to confirm ID and appreciate the quality of images and presentation.

As far as id confirmation is concerned, I always check before adding a post to efi site.

If there is some issue with id, I always give suitable feedback.
