I need to enable iframes since it appears I am unable to use thread wikis or member summaries. Reference this thread about vanilla supporting wikis - http://vanillaforums.org/discussion/27983/thread-wiki-or-member-summary#latest
I plan to manually just add an iframe to emded a mediawiki article in the thread if the OP requests it. I'm assuming there is no admin interface to the HTMLawed plug-in since it's hidden. Any details on exactly what files I need to edit would be great.
