I need a custom plugin for my Wordpress blog to change it to an online magazine. What I am need is the ability to add another level of categorisation to WordPress, so one can group posts together into issues (as well as as categorise and tag them as one can normally. The user would need to be able to create new issues easily, and view a listing (an archive in WordPress terms) of all posts in an issue. Issues should also be listed in a sidebar widget.
It would be great if we can also have a page for every issue as "cover page" and display a list of issues in an automatically-generated "Former Issues" page. That page can be displayed in the menu as "Former Issues". But I am not sure how that could be done through the plugin. I am open to suggestions about this, so feel free to let me know what your ideas are for doing this and how much it might add to the costs.
By the way, the plugin needs to be compatible with Wordpress 2.5.1 (the new version). You must be able to start working on this project quickly, once selected.
