I noticed that the links on this forum override the forum itself. And even worse, if you make a post that contains links and you click on them while doing a preview, your post is gone because the window gets redirected to where the link goes.
I had the same problems on my forums and theres a simple tweak to solve it. You can find the info on this post, including a link to the original tweak: Outgoing links opening in new window
And if i were you, make that change, so links on the forums will open in a new window, and people dont loose their post by accident.
