Dear ${admin_name},
you are receiving this message because your are the admin of the blog "${blog_name}"
${blog_url}
We are in the process of removing the NextGen Gallery Plugin and converting all existing
image galleries to the standard Wordpress media manager.
In your blog, we have found that the following posts include NextGen Galleries that should
have been converted:
${post_list}
If everything went well, you do not have to do anything at all.
Please check that the images are showing correctly, and let us know if something went wrong.
with love and +kaos

Caro ${admin_name},
ricevi questa email perché sei l'amministratore del blog "${blog_name}"
${blog_url}
Stiamo per rimuovere il plugin NextGen Gallery e abbiamo trasferito tutte le gallerie
di immagini al gestore di media di Wordpress.
Nel tuo blog, ci sono i seguenti posts che includevano gallerie di NextGen e che sono
state convertite:
${post_list}
Se è andato tutto a buon fine, non devi fare nient'altro.
Controlla che le immagini si visualizzano correttamente, e facci sapere se c'è qualcosa
che non va.
con amore e +kaos
