What kind of support do you offer?
Apart from the tutorials, you can write a comment on the S3Media LinkSafe Lite page or send us an e-mail. We typically respond within 24 hours although we give priority to customers of S3Media Stream.
You can contact us via support [ad] wordpress21century.com should you run into trouble.
We ask you not to post questions on WordPress.org as we won't be able to follow it up there.
There is also Premium support available. See "Can you help us configure the S3 account?" in this FAQ.
