I am not being able to add more people to the same conversation. I Was able to do it only one time, but there is as 5 people limit. I tried opening another conversation with more 5 people, but even using the auto complete function of the messenger I get the error "invalid node id specified" Also, please remove the 30 second wait between messages, it is very annoying... I now have to send PMs to almost 30 people and wait 30 seconds between messages. I don´t understand this limitation, for the search engine too the same 30 second wait. Wasn´t it a limitation from the old forum system? Why inherit that?
