I reckon there are a lot who just use the site for the How To section and have a nosy without contributing.
I see a lot of names of members who are logged on and obviously viewing threads but again making little or no contribution. As seasoned MG F/TF ers they perhaps don't need to ask advice very often and once good advice has been given feel no need to simply repeat the previous answer.
I am glad that this site, generally, doesn't attract the keyboard warriors who post endless c**p, argue and spout rubbish they once saw some other forum warrior write, repeating it as if it were the gospel truth.
A lot of posts are started by just a very small number of people and when they go quiet for some time or move on it appears the forum is quiet.
On here you get good advice from knowledgeable people and a good atmosphere.
It's quality not quantity that counts.
