Hack 1 Users might like to be able to read the reputation comments when they elect to turn off the "Show My Reputation Level".
Go to AdminCP >> Plugin System >> Add New Plugin

Hook position: usercp_start
Title: Always enable Rep Comments
Plugin php code:
$vbulletin->userinfo['showreputation'] = true;
------------------------------------------------------------
(I posted above one line hack and felt so dodgy about it. So I have now made a proper hack to share with you.):)

Hack 2 Users often see "Spread your reputation around before giving to the same user" message. This hack shows them the message, however the user can still submit the reputation comments without adding reputation points.

I have made this hack using the new vB3.5 RC1 Product Managament System. All you need to do is downloading the xml file and import it into the Product Management System. There is no need to import Plugin, phrases, template separately. They are all included in the xml file.

To Install:
------------
Download the zip file and unzip it into .xml file

Open AdminCP

Go to: Plugin System >> Manage Products >> [Add/Import Product] >> now upload the xml file. That should be it.
