Showing that the plugin developers are not far behind in the new upgrade to WordPress 2.0, many developers have updated their plugins for the new release. One such plugin is subscribe, now subscribe2.
This version has been written to work with WordPress 2.0, and includes a number of significant changes. Most exciting of all is the elimination of the subscribe.php helper file. subscribe2 now uses a simple token, , inside the body of any WordPress Page to display the form and handle confirmation requests. This should (hopefully) put an end to the sidebar and theme issues!
Additionally, version 2.2 trims down the complexity of the Options screen, and presents a vastly improved Management page. You can review your subscriber list in a number of ways, based on public versus registered user, as well per-category. You can send an email to various combinations of your subscribers under the Write->Mail Subscribers menu.
