RSS Channel
-----------
Assuming you have several blog entries, click on the title of the
search box in the left column. A larger search box should appear. Enter::
Any X ORDERBY D WHERE X is BlogEntry, X creation_date D
and you get a list of blog entries.
Click on your login at the top right corner. Chose "user preferences",
then "boxes", then "possible views box" and check "visible = yes"
before validating your changes.
Enter the same query in the search box and you will see the same list,
plus a box titled "possible views" in the left column. Click on
"entityview", then "RSS".
You just applied the "RSS" view to the RQL selection you requested.
That's it, you have a RSS channel for your blog.
Try again with::
Any X ORDERBY D WHERE X is BlogEntry, X creation_date D,
X entry_of B, B title "MyLife"
Another RSS channel, but a bit more focused.
A last one for the road::
Any C ORDERBY D WHERE C is Comment, C creation_date D LIMIT 15
displayed with the RSS view, that's a channel for the last fifteen
comments posted.

of blog entries, thus providing a RSS channel
