I was looking at the Road Map a week or two ago and could have sworn the Wiki was in there for RC1. I look again today and I can't find any mention of it.
I too am looking forward to the wiki and the forums. The blog would be a good thing too since we are pointing to typepad right now.
XWikiPortlet was in the roadmap and was pushed off. I don't have a time for its completion and probably will not be done for final. Decisions in what we were going to use in-house for hosting the JBoss Forge site affected it.
An important Forum Search functionality is available on jboss.org but not in the Forums portlet - can someone confirm?
I confirm it has not been ported yet.
