BOAC,
Much as your vulnerability warning efforts are admirable, I would think you're putting yourself in a risky situation where people might start relying on you to issue the advisories ?
Given the number of combinations of different software and different vulnerabilities you're going to have to start doing a lot more posting than you are at the moment to keep up with them all.
Personally I would think the mods would do better to put a sticky at the top of the C&I forum giving links to well known sites that activley maintain lists of current security vulnerabilities (or "security advisories" as the software developers prefer to call them) .... as well as a set of FAQs which seem to come up time and time again here on C&I.
