Looking for people

Dear Lazyweb,
At the poppler project we are trying to relicense all our patches as GPLv2 or later so that in case that xpdf is ever relicensed to something newer than gpl2 only we are not stuck because of patches.
The problem is that we have problems getting answers from everyone, so i'm posting this so that in case you know some of the missing people in person or have IM adreses of them, you can bug them for me.
And now onto the names:
- Marco Pesenti Gritti
- Kjartan Maaras
- Timothy Lee
- Carl Worth
- Ed Catmur - specially problematic has his mail server bounces mails
