I wrote the "Metis" module for a non-profit project I'm collaborating with. Now I'm working on an upgrade of the website to Drupal 7 and I need to have a D7 version of the module. But I'm not a very experienced module developer, which is why I'm seeking for help.
The module isn't really complex. Basically, it provides a field (in D6: CCK field) that contains a checkbox and, if activated, saves a so called "metis code" to include it in the HTML source.
