Alex, actually my permalink setup was not the default, it was the day-and-name choice (2nd, below the default).

So I’m thinking we’re probably not yet at the solution of this potential-non-bug

The database you sent me and the blog you gave me access to were definitely configured to use default setting. I switched them to day-and-name which made it work. That’s when we found you needed to configure your .htaccess. If you want to check please switch back and let me know but I just tested your database again and it works fine in day-and-name permalink.

No problem… We know how it works well, and thats all that matters. Everyone should use a setting that’s different than the default one and it will all work just fine.

Hi, I think I;’m running into the same problem. I tried with every setting of the permalinks, made all necessary changes to the .htaccess, but it boils down to this (permalinks are now day-and-name):
all sub-categories from domain-naming category go to subdomain/category/…., all other categories, tags and archives go to maindomain/category/…, maindomain/tag/… and maindomain/day-and-name/…

Could you give me a little more information on what you need in terms of site setup.
What categories do you need to be subdomains?
What is the address of the main wordpress site (http://articles.icmcc.org or http://www.icmcc.org)?
What currently happens when you try and set it up?
