This plugin will add a minimum and/or maximum limit of characters and/or words in posts for individual forums. This can come in handy to prevent those annoying short posts/topics, like thnx etc or extremely long posts.
To set the minimum/maximum of characters and/or words, go to the forum in question and enter the amount of characters and/or words under the Minimum/Maximum Characters/Words. At the plugin 's setting you can exclude a group or groups from this restriction.
