Will someone please explain in simple terms (i.e., this is step 1; this is step 2, etc.) to antique people like me what we’re supposed to do?
1) Sign up on twitter.
2) Go to your settings and change the time to +3.30 GMT Tehran
3) Find people/groups to "follow" (ie. go to http://www.twitter.com/Jeff_Head) and click "Follow" under the pic. Start posting comments in your "What are you doing Box". That is a "tweet", you can use commands (like @username message) to post to specific people, or like (#discussionname message) to post to discussions. It gets quite addicting. Live feeds, unedited news from around the world.
4) Use common sense and be careful and it is surprising how much you learn.
And, the more you tweet under that time zone and location (+3.30 GMT Tehran) the more you will confuse the Iranian government goons and shield the Iranians trying to get the word out
