[Seaside] Pier questions

[Lukas Renggli]

Hi Noury

> Hope this is the right place to post a question about Pier.

Sure, that's fine. There is also a dedicated mailing list, see here:
<http://www.piercms.com/contact>.

When you edit the post there is an input field for tags. Just add the
tags separated by spaces.

There are several widgets that go together with the blog. Go to the
environment of the blog and add the widget "Tags" in the section "Pier
Blog". You can see an example of this widget on my blog
<http://www.lukas-renggli.ch/blog>, along with the "Archive" widget.
Go to the settings to change the preferences of these widgets.

All executed commands are logged in the history, if you enable one of
these persistency strategies. This includes adding, removing, moving,
copying, editing, chaning the settings, ... of a page. The number
given in that settings says how many of these commands are remembered.
They are used to generate RSS feeds of the changes and can also be
used to restore previous states. To see a list of changes go to the
changes view.

Cheers,
Lukas
