Best bet is to find a few other guys interested in the Mossie and start up the squad with a few die-hards to get its name out there for a tour or two. Even if they eventually go back to other squads, getting the name out there for a few weeks or months would probably help, especially if you let newbs know that you are open to recruit them. Seeing the name show up in the buffer with kills is the best recruiting tool, especially if you see a few names show up at the same time.
Good luck in getting it going someday, love seeing the Mossie raids. I'd offer to help, but I only fly planes with single Merlins.
