Updating the Wiki?
There are guidelines, they are found at Article Guidelines. They don't really apply to the changes you're suggesting though, because you're just going to go in and change some text.
Everyone can edit the wiki. That's why it's a wiki and not a standard website.
Paragon Wiki: http://www.paragonwiki.com
City Info Terminal: http://cit.cohtitan.com
Mids Hero Designer: http://www.cohplanner.com
So this should probably go on the ParagonWiki forums but I couldn't figure out where to stick it...so I'm just going to drop it here and hope someone will see it.
Never having used a wiki before I'm not sure how to go about making modifications. What is the policy for changing entries? There are some entries that are outdated and wrong (and have been for a while now). Force Feedback Proc...I'm looking at you. Should I just go in and modify them? Is there someone that I notify? Are there formating guidelines somewhere that I need to follow?
The two changes I would make are
1) The Force Feedback proc no longer triggers a suppression period, it simply ignores all procs while the power is active so the lovely graph that is up there is no longer true.
2) The changes to the Aegis IO did not make the bonuses global. The 3% Psi Resistance is, but the 20% status protection portion boosts your status resistance for 10 seconds. (Like Numina except 10 seconds instead of 120)
