[opencms-dev] Automatic copy of recent published news in another channel

[Salvador Santander]

Hello. I have three channels: service notes, news and last news, and I want
that when somebody publish a new in the two first channels mentioned, the
new be copied to the channel "last news" or another posibility is that the
channel "last news" can read the recent news of the other two channels. Is
this possible? How can I do it? Have I make my own news module? Thanks.
