I cant vouch for whether the site mellowing is down to the addition of CSX owners or not but I would respectfully suggest that there are good and bad owners in ALL camps, be it the originals, Kirkhams, CSX, FFR, Lonestar, et al.
I doubt it is so easy as to simply increase membership from one manufacturer of replicas to mellow the site.
Aside from which I think the site is fine and is in no need of 'mellowing'.
