SohoNYC, sorry for the delay in responding: we've had many thousands more messages than usual in the last week, and our support ninjas have been working very hard to catch up. They're getting there, but they're not there yet!
Jen71, OmniFocus can synchronize its data with a web server using the WebDAV protocol, but we don't provide the web service. The easiest option is to sign up with Apple's
Mobile Me service, but you can also sign up with other services such as
BingoDisk or
bluehost.
(Or, if you're technically inclined, you can set up your own WebDAV-enabled web server on your own computer. There are some other threads on this forum that go into more detail about how to do that, but it isn't an approach for the faint of heart. We're also looking at making it easier to sync directly with OmniFocus for Mac without an intermediate web server, but that's probably a month or two away.)
