Hey tack,
You definately have a great opportunity to build great maps using your real-life expertise with the enviroments that are ofen depicted in PR.. That Being said, mapping is tough and often frustrating work! but well worth it!
Try the tutorials in the Modding section of these forums as a start and, as always, you are welcome to post in the suggestions thread about specific ideas/comments/critques of maps already made ***** but be constructive, not destructive, as mappers spend hundreds and hundreds of hours working on them
To be honest, the best thing you could provide to the PR team (if your not going to map yourself) would be to post up some pictures of your home community and share with us some stories that could be used in PR.. if anything I would like to know more about Iraq and its people from a reliable source (rather than from Fox, CNN, or the likes)
just a thought, and welcome to our community!!!!
