When the most recent OmniWeb update was announced, I skipping reading the description of changes and proceeded with the update. I expected I could read the description of the recent changes in OmniWeb's Help > Message of the Day.
Ooops! It's OmniFocus that has Help > Message of the Day.
Some prospecting of the OmniWeb Sneaky Peek site uncovered the
OmniWeb Message of the Day page. This page appears to be the be the foundation for an integrated Message of the Day feature in OmniWeb. (Don't bookmark this page -- it's release-specific.)
Until Help > Message of the Day arrives, I've bookmarked the
OmniWeb Sneaky Peek Builds page. The "Release notes..." links display the Message of the Day for each release.
