PhpList *appears* to be sending to a huge list instead of the selected lists?

Thanks Dan,

From the ~4000+ people list I have not had a single email as feedback so I wonder if anybody got it.
From the translators I have had several emails already. So some definitely got it !

You think the upgrade might fix this weird behaviour ?

How do I make a backup of the database ? What type file is it and where should I look for it ?

Is there a text on how to upgrade ?
It’s been so long since I installed the latest that I forgot how to do it.
