Is the Wiki (wiki.pentaho.com) accepting contributions from community members?

Browsing anonymously I don't see option to make contributions ('Edit' option not available as hyperlink). I tried using Log In link but don't get authenticated with either my Forums info or JIRA info. Couldn't find any way to create an account on wiki, nor did I see specific mention in the 'How To Contribute' wiki section or through searching this forum.

The wiki pages are usually top-ranked for search engine results; there are times where I frequently google a Pentaho functionality question (i.e. PDI Steps), go to the wiki page, don't find answer, but later do find answer elsewhere. It'd be useful to add that info back to the wiki in case others have same issue.
