Exporting Your Account
Long time Readmill users should probably look into exporting their account details, which can be done here.
There's no easy way to export your entire Readmill history so it can be imported elsewhere, but you can export a reading journal that summarizes the time you spent in Readmill. There are also an option for exporting your review and reading history so it can be imported into Goodreads or Booklikes.
Salvaging Your Library
Once you've started the process to export your account history, the next step is to rescue any ebooks you uploaded to Readmill. If you go to the export page and scroll down, you'll see an option for downloading your Readmill library as a ZIP file.
Click it, and then scroll down a little further and read the instructions on how to transfer the DRM licenses. I for one would not have transferred any DRMed ebooks to Readmill, at least not intentionally, but even so I would still go through the steps to transfer the license (better safe than sorry).
I would also suggest transferring the license sooner rather than later. Readmill isn't scheduled to completely close until July, if the DRM causes issues then it might take a few tries to get the license transferred.
Where to go next?
Once you have the DRM issue resolved, the next step is to look for a new home. I'm not much of a social reader, so I am going to leave this open to the comment section.
What's a good alternative to Readmill? I know that both Kobo and the hated Kindle have some social reading aspects, and a couple different reading services similar to Readmill have come across my desk over the past few months: Fastr, Bookmate.
Has anyone tried either Fastr or Bookmate? What did you think?
Is there another service which I have not mentioned?
