I noticed that on two web sites I manage that the page loads always hang on the Gravatar.
Neither site has a blog but uses Wordrpress as a CMS. I opened as many files as I thought necessary and see pluggable.php is the one that contains the gravatar links.
Since I don't actually need Gravatars, can I just remove the six references to Gravatar?
Lines are 1703, 1706, 1708, 1712, 1715, and 1717. I realize that I will probably need to do this over again when WP is updated.
