Hey! Welcome to Cruisemates! Be sure to check out the "Carnival Roll Call" thread at the top of the main teen forum. This roll call is "sticky" and is always available. Post your cruise details in there and it'll be guaranteed to be at the top of the page every day until after your cruise has sailed.
If you have any questions ask away! I'm Ryan, one of the senior members here and you'll meet Mike our Teen Host soon as well. There are a lot of cool people here to meet and discuss cruising with so make yourself at home!
