Hello! I'm new too and i cannot post new thread as others, so i did ask to an admin about that, and got this answer, maybe can help:
"you need to make a couple of posts in existing threads before you can create a new thread. (Not sure how many though, something like 5-6.)"
Got the answer from MadDogX (thanks!)
Apart from that i'm a 37 year old guy from Italy, that enjoy Arma 3 a lot, and my english is crap!
Have a nice day all
