Ballad Gal, as I had thought was possibly happening... because what Greg posted was a COMMENT, it apparently does not get listed within site searches.
That's one very good reason for if: if you have something that might be important or helpful to ask or answer in a Group, don't just post it in the Comment Wall. It'll be impossible to find after a year or so as it gets buried underneath newer comments. Instead, please start a new Discussion in the Group with your helpful posts on a subject. That way, the discussion's title and posts DO get indexed in site searches.
Comments on Comment Walls are intended as just passing insignificant chit chat kind of stuff. Trying to hold a conversation of any importance on a comment wall is a futile exercise... that conversation is 'doomed' to disappear.
Start a discussion thread in a Forum or in a Group and it'll be there nicely indexed soothers can find it in the future!
Hope that helps. Thanks for the update!
You're Welcome, Strumelia! Good advice for everyone about not posting on a Comment Wall. I didn't realize that could be done until just now when I looked back at where I found Greg's explanation and saw that there is a place to do it.
