Don't be afraid to take the initiative dude and post up on the forums that you'll be on at whatever time and ask that if any CAG are around...you'd like some help with your marksman. We are all here to help and will generally respond to such threads. Just try and ensure your threads are in the correct forum ;-)
Don't be afraid to get involved on here...you won't get any grief, if anything is wrong or out of place, you'll be advised but in a friendly, non aggressive manner. Don't be shy.
We all family here...and you get out of it what you put in :-)
If you need help, we're all here and available on private message or xbl.
