Activity Reminder Message
Download this mod
This is one of the options I missed a lot when converted to Smf. So I coded it for my forums and now I packaged it and upload it here too to share it with everyone else.
This will give you the oppurtinity to show a message to your inactive users with low post counts to become more active. The add on is fully configured at Admin->Panel->Modification Settings->Activity Reminder Message.
You can use html and smileys in your message. You can also choose where you want the message to show, in index page, footer or both.
