This extention create new topic when someone register in board and signs in. this can be a welcome message topic or anything that make new user active and responsive.
the main problem returned by users of your extension, is that the author of the welcome topic is not a user that the administrator can configure, it’s the new user registered.
Could you make in sort that the topic author can be configured in the ACP to allow to set a real registered user, like “Board Robot” or “Welcome Robot” ?
