I want to use the NIV / NLT / NKJV / other version...
The NIV licensors, Hodder & Stoughton, require a significant minimum payment before they'll allow us to use that version, which would be not viable for LearnScripture at this point in time.
The copyright holders of NKJV would like a much large user base before they allow the use of that version.
If there are other versions you would like, please contact us. However, it always depends on getting the agreement of translators/copyright holders, and we have to wait for their timing too!
The site memverse.com has a larger user base and offer a much larger range of versions. The workflow and interface for learning is quite different from on LearnScripture.net, but obviously works for a lot of people.
