Next up to get it on your Sidebar using the widget Framework, i added a new widget, HTML
Then added this code to the HTML part changing the red and blue for your needs:
<span class="smallfont">Contribute to the Forum for help with our hosting costs, maintenance costs. Please Click the PayPal Logo to Contribute, Thanks</font></b></span>
<br /><br />
<a href="http://www.yoursite.com/donations/" method="post" target="Contribute"><img src="imagepath/paypal.png" border="0" alt=" Contribute"/></a>
So the above finally gave me what i wanted, and maybe what you want.
When you take away the nav Tab link then that is the link to take you to the correct page on your forum instead of clicking the Nav Tab, you only need to change thehttp://www.yoursite.compart, my mistake, then the /donations part stays the same at the end of the url to take them to the donations page....
