Re: [Devel] why is it?

Oops,

Sorry, my mistake, I hadn't noticed the huge attachement when I approved
this e-mail through Mailman.. This shouldn't happen in the future..

By the way, a lot of un-suscribers still send mails to the list and
I need to manually filter them. I could however completely ignore
them in the future (since there is also *so much spam* coming)
