Certificates

When I rejoined EvE I noticed there were these weird little things called certificates on my character sheet. I looked into it and found out that certificates are a way of collecting up the skills you have and showing other capsulers what you can do. They also give a path for future skill training. They list which ships they would be good for. They are even broken down into classes; like standard, elite, ect.

Does anyone ever use Certificates?
Do you collect yours when they're ready?
Do you list them out publicly?

I do. I love the certificate idea. It's like having a resume readily available for future employers right there in game. On the other hand it tells your enemy (if you keep it up to date) what your abilities are.

I still like the concept and think CCP should explore and expand upon it.
For the newer players out there look through them, they could help you when planning the massive amount skills set out before you.
