Thanks @tyme for your response. The keyword search not working is troubling as the metatags in your word cloud are by no means comprehensive enough or detailed enough.  I can understand re username but it does limit ongoing connection with  people we've connected with  especially now that long continuing  threads are actively discouraged. Re who's online I've noticed that the list no longer includes the SANE team members but I guess if we don't know who's on shift we can tag the moderator. It's just nice sometimes to tag a team member when we know they're likely to be able to see  the post soon and respond rather than waiting days.
