Hi traumschule, I'd suggest being careful. Wikipedia has made it pretty clear in the past that they don't want us to take a hand in maintaining tor related pages. Roger has had frustrations on this front, and my account got banned when I corrected links for one of my projects...
Personally I'm still pissed with that Alexf guy. Eventually by serendipity I crossed paths with a couple other (much friendlier) Wikipedia admins at a tech meetup that unblocked my account but cautioned me that we should only leave notes on the talk pages - not directly edit pages ourselves.
Some suggestions from the list. It's generally good to prepare changes with references to a credible source (not our pages) and get in contact at #wikipedia when in doubt.
I recently reviewed the English Tor Wikipedia page as per our conversation at the last meeting. All and all, it was accurate; there were probably some parts that were understated and others that were overstated, but there was nothing too glaring. I'm not sure who will be dealing with the changes, but I can chat with them as well if further information is needed.
I did have a few suggestions, though they mostly pertain to formatting and elaborating on existing content:
'Tor Browser' header could use a more concise explanation and feature list
'Third party applications' subheader could use some loving as you can see
'Levels of Security' header - why is this a million miles below the browser section? Could use revisions as well
'Tor Messenger' bar should be removed - as it's no longer current or reccomended, it would be better to not showcase it any longer.
atagar is right. people who are officially part of projects are not supposed to be the ones maintaining the wikipedia pages for things. if a member of the wider community wants to work on this, that would be awesome.
