is it asking for a CPID, that means its wanting to know what you want your callsign or ingame name to be... like mines Iceman24, make something up u like, if u ever want to change it, its not hard, you lose your score for the month once you change names but it can still be done if you put something you don't like... Try not and put something like 88726635 as your callsign, cause when someone gets on the radio tring to tell you theres a bogey on your 6 there gonna have to read out all those #'s and will eventually quit tellin him because they get tired of callin out those #'s, its allot easier for someone to go,"hey Ice check your 6, or hey Ice that bogey is comin back around you need help... than it is to say eight eight seven two six six three five check 6... see what i mean.... you can put #'s in your name, just make sure you pick something that everybody can easily read quickly and translate onto radio quickly... theres nothin worse than seeing a bogey come up on some guy that just wrote saijdfdiews as a name, and you gotta stop thinkin about the bogey behind on top of below whatever and try and say his name over the radio... I think everyone should take that into account, cause theres lots of ppl playing that have funked up names that nobody can say lol all you guys can hope for is a programmed check six ( there is a feature in the game called check 6, and I have no clue what its default key was, I have it on my stick now, but if you see a bogey comin up on someone you just push that button and a lil box will pop up around his name, if you push it once a computer voice will come up on his end saying check six and he'll get a white message on his screen saying your name and check six, if you push it more than once it will switch planes, in case you are flying with more than 2 ppl, I highly recommend you program that to your joystick if you can, makes it easier to do, also never rely on a check 6 from anyone, always be lookin around, its called SA or situational awareness and you can never have enough of it, its all about keeping track of all the bogeys, where there headed, what alt there at, how fast they are going, and then the same to you, how fast your goin, how far away they are, how much alt do u have.... good pilots can keep track with 5 or 6 bad guys circling and loopin around em
