Not everyone uses the forum, I'm having same situation for my hol to the Cilento Coast (april 28th), know a decent number are booked but nobody replying to my post on the forum yet. Same holiday a week later and a few are on the forum, just how it goes sometimes.
You'll soon make plenty of new friends when you meet your travelling companions at the airport, don't worry they'll all be there.
Have a great trip.
