any ideas?
If you are looking to directly access stories on SOL from your e-reader, you probably can't.
However with a premier membership you can download stories as an epub or mobi and upload the ebook version to your e-reader.
What type of ereader do you have?
Storiesonline (finestories and Scifistories too) doesn't have an API for third party apps to connect through. So you can't 'connect' an app to SOL.
However, with a premier membership, you get access to ebook downloads. EPUB and Kindle formats are provided.
