I just installed this and only new content is appearing in clouds evne though old content is linked, how can I get my old content in the clouds?
You will have to rebuild your search index for the content type that you want to be loaded. At the moment only posts, profile posts, and resources are supported. More content types will be added upon request.
Will users that watch a tag receive duplicate alerts if a post is made in a thread they are already watching with a hashtag that they watch?
They will not receive multiple alerts. I make sure that they haven't already received an alert for that content. This prevents them getting an alert if they already were alerted of the post in any way.
