I think the 'One post wonders' (I like that) is common across all forums.

One of my pet hates generally on forums (well not hate but you know what I mean) is when you give advice to a newbie and you can see they are not only on line but looking at 'their' thread. As soon as you reply they disappear. I see that time after time after time. Sometimes they do return a few hours later, or even days sometimes to say thanks. And sometimes not.
