Oktay answered us, and he put the new DNS in place. So we now have control over the sylpheed.org domain. It is slowly going live as DNS servers notice the change…
I hope everything will go fine! Probably we’ll be able to replace http://sylpheed-claws.sf.net/ by a redirection to the new http://claws.sylpheed.org/.
If someone wants an @sylpheed.org email address forwarding to pop account, let me (or Paul) know!
