What does the message "Contactname has been removed" exactly mean when you have the option in Stuffplug NG on to tell you when people open/close your convo?

Note that its not they have left the convo because that message is "Contact name has left the conversation"

If you are in a conversation and and you don't talk to each other for a while (5 minutes, I believe), the server considers your conversation as finished and closes the conversation, to save bandwidth. This appears to you as such.

I'm not sure, but I think it's an idle message. It usually appears after a certain period of inactivity in the conversation. It doesn't mean they left the conversation. Many times I've got the "has been removed" message and afterwards the "has left the conversation" message. So they aren't incompatible.

Thought that might be it but i just had to check anyway. Its less than five it happens after about one minute of inactivity, its just annoying sometimes. Thanx.

i think the chat diconnection time is different for each country, so that might be why your get that message after a minute already

i thought that msg appears because the contact has minimize the chat window
