Can I remove the "Powered by" link
Yes, you can remove it. However, it would be great if you can promote JReviews to everyone you know or provide credit in some other way to help us with the traffic to our site so we can continue providing excellent support and upgrades.
With JReviews 2.5 we introduced a new setting to hide the credit. You will find it in the Configuration/General Tab under Theme Settings. If your version doesn't have this setting you can upgrade or follow the instructions below.
Edit /components/com_jreviews/jreviews/views/themes/default/elements/credit.thtml
And remove the following code:
<div style="margin:20px 0 20px 0;text-align:right;font-size:85%;"> Powered by <a href="http://www.reviewsforjoomla.com/" title="Joomla CCK and Reviews">JReviews</a> </div>
Do not change the text to Powered by XYZ, it goes against the license terms.
You can make this change once and not worry about it on upgrades by using the JReviews Code Overrides feature.
