Beta 6 also introduces the use of
rel="nofollow" attributes on external
links in wiki pages to reduce the effectiveness of wiki spam. This will
cause participating search engines to ignore external URL links from
wiki pages for purposes of page relevancy ranking.
How is the per-project option coming on this?
Still there, same as it's always been.
As you're aware, there's no hurry here. The attributes cause no harm to
the functioning of the wikis.
