To the membership:
. . . the only thing I can say is, please don't do this. If you have a topic you wish to discuss that has nothing whatsoever to do with a topic that's ongoing then create a new one, and in the appropriate venue, be it the main group or the chat subgroup.
A recent double hijacking has been observed and the offending member notified that this is not something that's acceptable to do, ever.

A great deal of intelligence can be invested in ignorance when the need for illusion is deep.
