I was under the impression that amxx.cfg got executed before any of the plugin's were initialize. So the register_srvcmd wouldn't be valid at that time. Thus you'd need to call amx_imessage and amx_scrollmsg from somewhere else after the 2 plugins were initialized. Also the initializing of the different imessages need to get into imessage's g_Messages[MAX_MESSAGES][384] array somehow. This must be accomplished somewhere else.
