Perhaps the security forum idea on this site can be satiated by Ubuntu's Security Forum
@Glenn points out ... "influx of new Linux users posting on UM's forums"
@alpinejohn states ... "Lets think about the subject and the audience."
@wolfman thinks ... "wise to have a security advisory guide" & "I don't think it warrants its own section"
@tiox states ... "Having a security section would certainly keep things "neat" "
@maro thinks ... "I find this topic to be too important to neglect it or even sub-categorize it"
Quite possibly the name itself needs refinement - perhaps Safe Computing for MATE as a general heading.
My idea is to educate ... it's much better to be proactive than reactive. To quote a famous clothier, Sy Syms, who coined this as the company slogan
"An Educated Consumer is our Best Customer".
I suggest we adopt this sentiment!
