As noted on the Nicecoder forum and found elsewhere, the wordpress integration for IndexU is an excellent addition for any IndexU site.
Some users have asked me recently about the WordPress integration and WordPress 2.5x, so here are the results of my testing.
Recently WordPress was upgraded to a new version with a large number of changes. The good news is that after testing, IndexU users can upgrade to the 2.5x versions of WordPress without worry, using the old instructions.
