Twheran
Many people have already posted about the greening of our twitter icons (which shows visible solidarity, but has no other effect), but here is something you can do that will make a difference. Change your Twitter location to a city in Iran and change your time zone to GMT +3:30, making “it harder for the Iranian government to block real Iranian Twitter accounts”. It still may be a small gesture, but worth the extra time it takes us.

Done. But I took the green off my avatar bc it erased the avatar and I just had a little green square which looked really pathetic.
Or, if you have access to a server, this might be a good thing to do.
