I have installed a new plugin to the forum to prevent newbies from posting to wrong forum.
With this plugin, new users will need to confirm the destination forum for the new threads
if their post count is less than 5. If member is not in the correct forum, he will be able to choose a different one from a drop-down menu, then continue with posting.
Below, you can see the screen shot of this functionality in action:
Let me know if you see any problems because of this plugin or if you have any feedback related to it.
Thanks.
