Hahaha, I saw someone browsing this topic from the userlist and thought 'hmm, wonder who's making a mission with our addons' - turns out it was me! Yes, I wouldn't hold your breath! I'd completely forgotten about this!
In the missing 4 years i've ended up joining UKF, joining the Army (and god, how incredibly naive my mission idea sounds to me now) albiet as a weekend warrior, and have gone half way around the world and back. Unfortunately the one thing I didn't ever do was finish this mission. Sorry!
