You may have noticed the 'banners' below forum members' usernames (eg. Gold Trader, BoTM, etc...)
There is also one available titled 'RetroBike Rider'. http://www.retrobike.co.uk/forum/images/ranks/rank_rider.gif
These are available only to those who have attended a RetroBike organised meet and ridden retro. If a member can prove their attendance at such a meet, they can pass their details through to the site admin (username: John) and request the banner be added below their own username.
