Tagging email subject line with something like [fbsd-questions]

[Amarendra Godbole]

Hi,

I subscribe to many fbsd lists through gmail, and am not able to
visually detect which email was sent to which fbsd list. Is it
possible to add a tag in the subject line, something like, [fbsd-q],
or [fbsd-questions], or similar so that emails can be visually
classified?

Given that these lists have been around for a long time, was there a
discussion on this? If the idea of tagging was dropped, can someone
inform me about the rationale behind this decision? Thanks in advance!
