Empty post box
When leaving a comment I didn’t enter text in the message box – I was taken to a Wordpress error page without any link back to where I came from. Had to use the browser previous page option to go back to the welcome page– shouldn’t ever have to use this to navigate around a site.
Is there a way to trap an empty or micro-post and return a message like " A post needs a minimum of 30 characters"
Any suggestions ?
