[ElleKayEm]

Did you download the epub with ADE or DeACSM? Did you add the key to DeDRM's customization or let DeDRM retrieve it automatically?

[Patitapetit]

@ElleKayEm All of now 74 issues will be unsolved?

[ElleKayEm]

@Patitapetit Why?

[j-howell]

I believe that Patitapetit is referring to the number of currently open issues.

[ElleKayEm]

@j-howell Yes, but why ask if they're all going to remain unsolved?

[j-howell]

And why ask in this particular issue? We will probably never know what was meant by that.

[ElleKayEm]

Probably just because it was at top of the list of open issues at that moment. (The next issue has already been resolved and closed!)

[j-howell]

It’s not as if the number of open issues actually matters. Most are due to a failure to read the instructions.

This would be a good time to acknowledge all of the effort you put into helping people here. I couldn’t answer the same questions over and over while remaining civil.

[ElleKayEm]

Thanks!

[NickFabry]

I second @j-howell - I’ve learned a great deal from your patient and informative responses to so many of the issues brought up here. Thank you @ElleKayEm !

[Patitapetit]

I supposed that nodrm/drm is a group of people who help another with problems with dedrmed. If someone ask and got an answer and dont return. Why keep open the issue?.

[ElleKayEm]

If the original poster doesn't close it themself, noDRM will occasionally come through and close things that appear resolved. But it's low priority. As far as I know, no one else has the ability.
