It was extremely busy, and lively about 20 years ago. Lots of healthy discussion. It helped that the WRC was in a really good place (though that wouldn't last). Other forums like Pistonheads, Autosport have rally threads and they're quiet.
To be honest, the issues are symptomatic of modern life; I've noticed it on other forums where newcomers immediately think they can 'rubbish' long time forum users, and show absolutely no respect at all.
