Redmine

Hi,

it's possible use an another calendar in redmine? I've a Sogo server with an calendar who use Webdav and i want to use this calendar in Redmine.

I know that exist a plugin to synchronize with google agenda but it's possible to synchronise with an another calendar ?

Is there a config file or other?

Sorry for my english but it's not my first language and i don't use english everyday

Thanks
