Hi all,
let me suggest you to take a look at the recent improvements to the feed manager, it allows paging, excerpt, selective publishing and so on.

You can put your blog in a page of your site and consume it in another page, for instance the main page, using an instance of feed manager. In that way you can assemble a news module very quickly:

1) Add the feed RSS of your blog in the feed manager
2) Open the "Edit feed properties" panel clicking on the pencil icon at the left of the feed you just added and select the option "publish as default", so you don't have to publish each article manually
3) In the "Edit Settings" of your feed manager instance set your page size number in the box "Items for each page"
4) In the "Edit Settings" of your feed manager instance choose what you want to show: 
       - only the titles of your articles (Headings only?)
       - titles + excerpt (you can set the length in char of excerpt and the excerpt suffix)
       - author
       - all the article

Furthermore, the feed manager is also AJAX enabled, so you can navigate trough each page without refreshing the container page.
I'm using it from a while and it works well ;-)

Hi Nux,

it sounds you have an older relase of mj. The new features of feed manager are available starting from 2.2.7.6 release

@Walter,

I have the lastest version, donwloaded couple of days back.
I have found the checkbox. You have to check first the "Enable Selective Publishing" propertie in the settings of the feed manager.
Then I got that "publish as default" checkbox on the settings of the feed.
But I still don't see any content :(
When I check that checkbox on the settings of the manager, I get links for "Add/Edit Feeds - Manage Publishing"
Clicking on manage publishing shows me nothing as well.
 

@Joe

Can you let me know where i can see if the site is running in medium trust?
Cause I have my own web server, and I would be surprised if that is the standard setting for a site on IIS.

Well,

I didn't do anything special to set it up on my server: it was just click and go, thanks to you ;)

But I do get an error:

(I also get errors from missing stored procedures like bannedIP and things like that, even this is a clean setup)
