Yep, I highly agree with gusreis and I hope we will see something changing in a near future.
Pro: Since most of the products are already linked to GitHub/GitLab personal pages it will be just a matter of copy-paste the product description from one place to the other.
Also, I have to admit that I struggled many times with BBCode in order to get a proper formatting for my products pages here on Opendesktop (and this is always --> Edit, modify the BBCode, save, reload, repeat)
Finally (but this is probably out of topic and more of a rant), I don’t get the point of using BBCode since there’s no real gain in terms of chars saved with respect to pure HTML. Markdown is a easier and clever way to get directly to the point, IMO.
