Our June release was just put up a week ago with feature updates as well as fixes.
At www.ribose.com you'll see our shiny new public site which foretells some design changes to come in the application. Public facing parts of the application have been updated as well, including the login page.
You can now see who you have invited to via People > Requests > Sent. For those who often use multiple tabs, no more missing new notifications and chat messages -- these events now show up in the title bar so you know something happening just by looking at the title.
Numerous bug fixes in Guidance, Chat, Tags and some security hardening.
We are still tweaking and adding stuff to www.ribose.com, feel free to send us an email email@example.com if you have any suggestions or criticism.
