I like your product better than other stuff out there as well but am concerned about the lack of maintenance for the plugin.
Are you still planning to update? Your post from a month ago says new version in one week. I have used this on many of my sites, but desperately need to update my maintenance sites to the new wordpress version and am concerned about compatibility. Plugin seems to have issues with newer WP versions. Randomly notification is not sent and this seems to be happening when ‘reply to submitted email’ box is checked. I have reported this issue and have even paid for support with no reply. I do SEO and conversion optimization and cannot use this plugin if we cannot be sure the client is get the leads the site is generating.
It looks like someone is at least responding to this thread. Can you please let me know your intention? I would really love to continue to use your plugin.
