Joint Post's......A way retain calm

Ok, so I've been noticing that some of the posts are becoming quite confusing with the multiple conversations going on in the simm and wondered if anyone knew how to utilise the "Joint Post" function on the control panel?

As this would alleviate a lot of the confusing issues that people may be having reading them....

So, whats the general consensus on them? As I know the old forum way was ever MORE confusing, but this could make posts better, and improve character development
