[GRASS-PSC] PSC management

[Markus Neteler]

Dear PSC,

I believe that we need to go on and start the process to
renew parts of the PSC.

List of current PSC members:
- Hamish Bowman
- Helena Mitasova
- Markus Neteler (chair)
- Massimiliano Cannata
- Michael Barton
- Scott Mitchell

Former PSC members:
- Brad Douglas
- Dylan Beaudette
- Paul Kelly
- Maciej Sieczka

In essence we have 4 slots available.

Now it is time to post a call for nomination to obtain a list of
people with recognized contribution to the GRASS project.
The proposer should nominate along with a small paragraph
describing why the candidate is proposed as PSC member.

I'll do so now.

Markus
