[opencms-dev] news channels

[Andrea Frittoli]

hi all,

I'm trying to understand who to use channels, I think they could be a
very good way to aggregate and filter resources, and I've got some
questions about them:

is it possible to create hierarchical channel for news entries?
how may I link one resource to multiple channels?
may I use built-in OpenCMS channel mechanism for news entries instead of
creating a NewsChannelContentDefinition?

any help would be greatly appreciated!!
