How to contact people in charge?

Hi,

I contributed using Paypal on 3rd Sep., but as I did not hear anything back, I decided to contact the email address associated with the paypal account. Sadly it's failing since a few days:

Technical details of temporary failure:

(0) swing.be. 217.19.237.54:25: Connection timed out

Daniel, are you following the activity here in the forum? It looks like that's it's your email address. Or is somebody else able to contact him using another means?

Thanks!

Alain

PS: I did not find any other contact methods on the website ...
