GetSimple Support Forum

I would like to know wheather GetSimple has any tool for this:
an end user writes announcements in the page A and other announcements in the page B and latest two or three of them from each page automatically appear (or beginning of them with a link to the full text) in the page C, together with the date of their creation.
Thank you.

GS has a number of tools for that.
