Is forum losing members?

[Amrod the Hunter]

When I look at member list,I see that many members didn't join quite a while.Also,many members make few posts and disappear.
Why is this happening?Are people losing interest for discusions,or maybe Tolkien is losing popularity?I know some people joined because of movies and disapeared,but many members that have been here for some time have left.
This forum is realy good-it has great topics,it's intelectual and it has many qualities.
But,I think that we should find a way to keep the new members here
What are your opinions and sugestions about that.
(If there was a same topic here,say,but please continue this thread,I want to hear opinions of this members that are here now)
