Hi folks,
I probably choose the wrong forum, but may be not :)
I'm developing a module (in C#) that communicates via RTC 1.3 (LCS 2005).
The communication is simple text one-way communication - my application server sends messages to my clients.
I'm triying to use MULTIPARTY_IM sessions to send messages to the bunch of users.
I create a proper session, add participants (checking CanAddParticipant==true) and send the message, but only the first participant in the list got the message. Others just not notified about message.
Can anybody provide a WORKING code (any readable language) for multiparty messaging? Are there any tricks on listening side?

Appriciate the help,
Vadim
