I tried to install your plugin WP Email on the latest version of WP.
I installed from the " plug ins " page on the dashbord, not the old way so I dont know know if that can have an impact.
It does appear in the dashbord left side menu as Emil options.
After the install, I did not see any "email this post" link on the posts or pages of the site.
So then I modified the index.php them file as explained in the instructions.
That still did not help the " email this post" link to appear...
What is not clear to me is if this should also work for PAGES ( vs POSTS).
And, I did not set the smtp server, login and ID because I wasnt sure what to use: my ISP's or the site's host.
The blog its installed on is sanfranciscoconsult.com.
