We've finished sending out links to the PDF version of Math Girls Manga Vol I, and as far as we know have responded to all bounced emails, reports of broken links, etc. If you haven't heard from us, or you're getting an error message when you try to download the PDF, please let us know at firstname.lastname@example.org.
As to the printed edition, we're done fixing what needed to be fixed (knock on wood), and have resubmitted the files to our printer. The files will go through a quality check there, then we'll be sent a proof to sign off on. How long this will take depends on how full our printer's current schedule is, but we hope that we'll have a proof by the end of next week. We'll let you know how things are going then!
Thank you for your patience! We're getting close now!
