I recently created a WordPress archive of my Twitter posts using the plugin and theme from Ozh.
Part of the theme was a sidebar posts archive which I quite liked the look of and have now extracted and turned into a WordPress plugin so I can use it on any site (including this one):
Check out the archive in action in the sidebar to the right below the Calendar and above the Tag Cloud.
I am thinking about releasing it via the WordPress Plugins Directory, but before doing so, wondered if anyone might be interested in doing some beta testing? It is a very easy install (upload to plugins folder, activate and then place widget in widget area) and currently has no options although I am willing to create some if necessary (such as the ability to change the display name).
The plugin only reads the number of posts and does not write back to the database so there is no risk.
If you’re interested in beta testing get in touch with me (by email if you have it or use the Contact page) and I’ll send you a download link (I’m not posting publicly as I want to keep numbers under control while it gets tested).
