You can now upload .DEK deck files in addition to text-format ones.
I've had a number of requests to share Magic Pro Tools draft data for various projects, from analyzing pick preferences to training draft AIs. Historically, I've generally declined these requests, because while I think the majority of users would be fine with it, some probably aren't, and I don't want to share data people aren't comfortable sharing. I've also avoided undertaking any mass analysis of drafts myself for the same reason.
There's a lot of interesting potential in these kinds of projects, though, so in order to enable this in the future, I've added a checkbox that indicates whether or not a draft can be shared. Drafts will always be anonymized before being shared, so your username (both your MTGO username and your Magic Pro Tools account ID) won't ever be shared.
Please let me know if you have any concerns about this.
