Confesions of a Noob

I first must say I am so impressed with subsim,you folks seem to be a very friendly and helpful group. That said, you can see I am a Newbie to all of this sub sim stuff. I love SHIII, I am hooked. I have completed the academy ( mostly satisfactory marks), and started a career ( at 29% realism). I am having problems engaging targets on the nav map. Will the " Nav Course Map Solver" by Capt America mod be the ticket for that problem? Again the site is very exciting, and please be gentle on this new hand on deck....Tnx
