Register to view all text
By Adrian at DevelopmentChat.com (http://developmentchat.com)
Tested on vB3.6.0, should work on 3.5.0 i think. : )

Updated version with enable/diable options via Admin Panel - http://www.vbulletin.org/forum/showthread.php?p=1077455#post1077455

Hey,
This is a simple little "trick", to think guests are only viewing part of the text.

All this does is add "Register to view all the text in posts. : )" under the actual post text.

All the post text is shown however, the message is "fake", but will hopefully trick your users into thinking it's real and therefore encouraging them to register.

It should look more convincing via the "..." at the end of the posts, to show the text has being cut off.

Installing
(Note: This template edit is the same for postbit and postbit_legacy)
Open Postbit templates > postbit_legacy/postbit (Whichever you want to use)
Find:
<!-- message -->
<div id="post_message_$post[postid]">$post[message]</div>
<!-- / message -->

Replace with:
<!-- Post extension -->
<if condition="$show['guest']">
<div id="post_message_$post[postid]">$post[message]...</div><div class="smallfont"><a href="register.php">Register</a> to view all the text in posts. :)</div>

<else />

<!-- message -->
<div id="post_message_$post[postid]">$post[message]</div>
<!-- / message -->

</if>
<!-- / Post extension -->

Save.

That's it, easy. ;)

Please click Install (http://www.vbulletin.org/forum/vborg_miscactions.php?do=installhack&threadid=126828) if used. :)

Thanks
