OK Jeff. I opened my Twitter Account and set it as you requested. Do I have to stay logged into twitter to be helpful? Pls advise.
I actually believe the best thing you can do is find people to follow and then start posting updates/tweets to them and in general, particularly to the #IranElection discussion. If you are logged in at Tehran at the proper time, the govt stooges there may see you...but if we flood them with updates and tweets they will have a harder time finding the local folks. That's my advise and what I have been doing. I believe now, after using it most of the day, that just being logged in alone is of marginal benefit.
I am at http://www.twitter.com/Jeff_Head and you can start there...or anywhere else.
