You have to wait for the next major release of PortaMx ... 
Fel
You gonna make me switch the portals? I'm always open for new stuff lol.
If you put the article feature like in simple portal, it would be cool if you add the ability to cut the article at where you want(by putting a bbcode or something like that) so you don't get limited by the global char limit, some need a longer overview text some need shorter. Yeah I know thats not the feature requests board but I just wanted to let you know

Althought, any moment that wordpress gets full integration support or a WP-like portal comes out, time for switch 
Out of curiosity - how will such a WP-like portal look like?
I was referring to a portal mod or script which would have an article system like wordpress but using SMF as the discussion place instead of comments and when you click "read the rest" button you go to the original topic, topics in forums may be sent to the portal homepage with a click etc.. The look of portal and forum don't need to match each other as I'm always up for some customization

Of course user databases and such stuff needs to be same, it just that you have a home page like wordpress's main page.
