Hearty welcome. It's always good to see new members, but since I'm partly responsible for bringing you here by bringing the video the community's attention, I feel bound to give some advice, which may or may not be worth what it costs.
The best way to learn is to read the site and forums. There's a wealth of information on everything from game walkthroughs and controls to the most minute WC errata. If you remember Claw Marks, the Wing Commander games have always had amazing manuals, and the
Manual Section has many of these. The best are, in my opinion,
Voices of War from Wing Commander Armada,
Victory Streak from Heart of the Tiger, and the
ICIS supplement from Prophecy.
There's also the wealth of files, many gigabytes of them, stored on the CIC's servers. You may want to start out with the
music section, which contains almost every track from every single Wing Commander game in some form, and the general
Files section. Afterwards you'll want to check out the
Holovids section with many, many videos of all types, from "making-of" featurettes to music videos (though unfortunately it seems yours has yet to be added.) The
Wallpapers section is a source of lovely artwork, as is the older
Fan Art section, and the
Documents section is a painstakingly collected and scanned archive of things that never were - games and television shows that never saw the light of day - as well as a fascinating look at the evolution of those that did. Of particular interest to many is the Wing Commander "Bible", which the series creators used as an internal reference from 1994 to about 1996 - although it's not considered canonical, it still makes for fascinating reading.
Although they're older and more familiar, the
Ships Database and
Articles section make for good reading as well, although the latter has some older, inaccurate pieces in it. The
Encyclopedia, besides being far from complete, is full of many, many spoilers, but it is a relatively accurate source for personal biographies and the like (far more so than, say, Wikipedia, although that isn't saying anything at all.)
Finally, the forums are the lifeblood of the site.
Read the rules.
I cannot stress this part enough. A lot of unnecessary head-butting has occured in the past because people skimmed over them while registering, ended up getting themselves chastised and then blew up in self-righteous indignation, often getting themselves unnecessarily banned as a result. Bans are usually very temporary things here, and you can usually get them removed by explaining yourself to an administrator in email, but like anywhere they're still something to be avoided.
Finally, this last part isn't really a pointer; more of a personal philosophy. You're certainly more than welcome to jump right into the fray, but I believe in lurking for a bit, reading old threads which often contain a wealth of information; basically getting the feel of the board, which in culture is far different from most of the rest of the internet. I think the old fighter pilot adage about one's chances of survival increasingly markedly after the first seven sorties applies here as well; your first few threads make or break you - but it's still possible to bounce back, as it is for old hands to fall. If you think you've found an angle on something that hasn't been covered before, by all means post about it; old concepts are constantly being re-examined as new discoveries come forth. It's a bit like history, really.
Good luck to you, and happy hunting here at the CIC.
