As Hornby continues to grow into the future it has occurred to me that the sub forums don't really - in my opinion - reflect the current output of the company and therefor what is in its commercial interest.
I would suggest that the General Discussion section be limited to 'modern' analogue models. This could be set at either 1980/81 (Hornby Hobbies & management buyout ) or 1999 (completion of move of manufacturing to China).
Creation of a sub-forum for 'classic Hornby' - all the legacy brands such as Dublo, Triang, Rovex, Thomas TTE and others.
Replace the TTTE sub-forum with Playtrains. This should be the way forward and the same way that PT should be an introduction to OO, a PT section will introduce users (and parents) to the rest of the knowledge available in the forum!
Not sure about Steampunk, but if it is further developed than a sub forum may be warranted down the line.......
Just a thought...........................!
