The Module Off is off to a great start. We've had more than a thousand visitors to the site, and 12 intrepid Drupalists took a shot at the first ever challenge. We've received a lot of feedback from the community, which we really appreciate. We're listening! Here's what we've done so far.
The first challenge called for a module that would add an AJAX-y link to a date field on a node display that would update the field to the current date. We had a ton of great submissions (which have all been published). After much deliberation, the award for the first ever Module Off challenge goes to theunraveler! theunraveler's module 'date_today' went above and beyond and was very well explained in his screencast. If you're interested in how to create AJAX forms, I encourage you to check it out! He'll be taking home a brand new Nexus 7 tablet! Congratulations! Big ups to tim.plunkett who receives an honorable mention for a really great module as well. Tim's explanation for some tricky parts to working with languages as well as his use of hook_field_extra_fields() is definitely worth examining.
Without further adieu, I present theunraveler's module and explanation video!
