I have add an attraction on my account but I did not made dollotrips, is it normal ?

Yes. You do 10 dollotrips just when you are the first to add the attraction on the website. If the attraction than you add to your account his already on the website, you did not made dollotrips but you can suggest this one on a trip and make dollotrips with the dollotrips award and with the vote than this attraction receive on the trip. Take note than for add an attraction already on the website, you have to pay 5 dollotrips.
