Essentially I want to duplicate the sitewide messaging notification functionality the private messages module. Instead, I want this clickable message (that takes an OG member to the post) to persist until a new comment or node in a specific OG is read by a member of that group. Then it disappears. Is this possible with the rules module?
I can easily create a sitewide message that doesn't persist, but how would you keep it present just for each OG member until it is read?
If this isn't doable with rules, is anyone aware of a module with this functionality?
Thanks
