Yes, and it's not that surprising. In fact, the number of people that have more than 1 post is 20687 - a measly 18% of the registered.

The fact is, it's really easy to register, however, it's much harder to take the time to write a post, especially if you've never posted before. Most people don't have the time or whatever. Such a statistic is not unnormal; most forums are in the same boat (or more likely, worse).

some of those registered users are really spammers whose posts have been deleted. I don't know if banned users are counted in that number or not. Some people register for the sole purpose of posting spam and have no intention of participating in DaniWeb community.

>I don't know if banned users are counted in that number or not.
Yes they are - when a user is banned, that does not mean their user account no longer exists, all it means is that they are unable to post (as far as I know; I've never been banned so I wouldn't know).

This is a common trend on all forums, like joeprogrammer said. Assuming most of them are not spam, it could be a situation wherein they come, sign up, find their answers, and leave.

Or they come, sign up, ask a question, and never return

no what i mean is that 2/3 of the forum have 0 posts whatsoever

Many people register, bash their head against the wall in trying to find how to "Post a new thread", give up. End of story for them...

What makes you think this? Serious question. I wouldn't have thought it was that difficult to post a new thread, and if they read the welcome guide it's even got a screenshot with a flaming big arrow pointing out which button to press.

As to the general join but not post thing, a lot of this can be put down to the lurker effect whereby people come to read rather than post. Not uncommon, and with a resource the size and nature of DaniWeb rather to be expected I guess.
