June Update

As has been mentioned in the previous updates, all of the digital files are complete and ready to send off to backers and pre-order folks. And this is coming. The hang up is two fold. 

One, not everyone has completed their BackerKit survey (only 75 left). That said, we are going to proceed. 

Two, my role and day job have drastically changed in a good way but due to a massively traumatic situation. Let's just say I am in a new role with double the responsibility (probably more like triple) but the reason I got the promotion is due to the spot becoming open in a traumatic way (it didn't help that the role I am stepping into was held by a close family member). 

All said, I am doing considerably well - but exhausted. Luckily all the work for ToaTD was complete, it is now just getting it to y'all. Tony and I are working on locking in orders and then boom! Files are in inboxes. From there we will give a couple weeks for folks to let us know of any typos we missed and then production begins! Thanks for all the support and continued patience!

Don't forget to fill out those surveys y'all. 92% of y'all are there! Also, make sure your addresses are correct as well. 

Did we mention the digital files are all DONE!!!

There will be a community proofing Google form soon too, so when we send out the digital files - please fine tooth comb the doc and let us know what we missed. Then, come July we send the final files out for production to begin!!!

16 Days left to Lock-In orders and Pre-Orders
