If your recipient is a registered Corlive.com user, and has marked the “public read status” in the preferences, then in the “sent” folder, you will see whether your message has been read.
Now, when you enter your contact list, you can click the “more…” link and then find messages from/to this contact. We think it’s quite useful, since we very often look for messages from/to somebody, and now instead of using the search tool we can do this much faster: simply click the “find messages from …” link. As always, please send your suggestions to corlive.com/admin
