rating in portal announcement

[RateU]

You can try this plugin (attached):

This plugin depends on XThreads. So, you need to install XThreads before using this plugin.

Reposition the {$portal_announcements_rating_rating} variable in your portal_announcement template as you like. If you can't find the variable there, you need to add it manually.
If you want to change the style, edit the cache/portal_announcements_rating.css file. Basically, the contents of this file is the same as the default star_rating.css stylsheet.
