Disable Signatures per user

Well I've been having arguements about signature sizes with a user of mine.
Usually I'd ban the person but maybe it would be a better punishment just to disable their ability to display signatures within the postbit and a few people have asked for this on vbulletin.org and even released a hack for it but i don't really want to hack when i could do it via templates just as effectively and then i decided to share with everyone here

This should work on any version of vb3

first create a new profile field

Title: Allow Signature
Description: Your Own Description here
Type: Single-Selection Radio Buttons
Options: Yes and on the second line No (case sensetive)
Display Page:	Edit profile (or anywhere u want)
Set Default: Yes
Field editable by user: No
Field Hidden on Profile: Yes
Field Searchable on Members List: No
Show on Members List: No
Allow user to input their own value for this option: No

make a note of the [fieldXX] number

Now Find in Postbit / Postbit Legacy

<if condition="$post['signature']">

and replace with

<if condition="$post['signature'] AND $post[fieldXX]!= 'No'">

and now

replace XX with the field of the new profile field

Now Open MEMBERINFO template and find

$userinfo[signature]

and replace with

<if condition="$userinfo[fieldXX]!= 'No'">$userinfo[signature]
<else />
<center>Signature Disabled By The Administrator</center></if>

 replace XX with the field of the new profile field and your done

you can now enable and disable signatures in the postbit via their user options
and the profile field will be hidden to all except moderators and above

In member info it will show disabled by the administrator
