We've had the Codex for over a year now and we had it exclusively be HTML codes due to some restrictions of the software we use here on the Initiative. We've been toiling over getting it to work since we originally implemented but we toil no longer!! We finally got it to work!
You'll see when submitting to the Codex that there is a new field "HTML" and "BBCode". Choose BBCode and Copy and paste your code as normal and the template, as always, will do the rest.
We look forward to seeing these amazing templates as you create them.
Regarding challenges. Unless otherwise specified in the challenge the challenges are meant for HTML templates.
Regarding the Submissions incentive. The page has been updated to reflect that BBCode templates do qualify but you need more BBCode templates to reach the goal.
