Custom Admin Footer Text lets you customize the left and right admin footer text. Overwrite the default text or links with anything of your choosing. Great for developers working on client sites who want to include support links, bylines or credits in the footer.
Currently the left footer says “Thank you for creating with WordPress” and the right footer shows the current WordPress version. For WordPress developers, this is a lost opportunity. Use that space to put links to your website, a copyright statement, whatever you want.
Use it for:
<ul>
<li>Copyright statements/credits</li>
<li>Link to support forum</li>
<li>Link to your other products</li>
</ul>
Or maybe you are just a regular guy who doesn’t like the admin footer. Put a link to your site or whatever you want to see.
