While I've been avoiding most of the current bruhaha simply by using my delete key, I have a simple suggestion. On other lists I belong to, when folks want to have discussions "off topic" that they feel might be of interest, they simply put "OT" before their topic in the subject line. This marker alerts subscribers that whatever follows might be a bit off the expected track. Either that, or simply use the delete key when a thread isn't your cup of cigar smoke. wb
