This website is being replaced by a new non beta website www.simpletext.ws. The latest version of WriteRoom.iPhone will sync to the new www.simpletext.ws website, not to this site. You will need to move your documents from this site (manually copy and past using a web browser) to the new site so that they will show up in WriteRoom.iPhone when you sync.
I will leave this site running for a few months so that you can get your data, but eventually I will shut this site down, so please move your data to www.simpletext.ws as soon as possible. If you have questions please post in the user forums. Thanks.
