I haven't seen or heard from our friend TIRDAD in weeks, I certainly hope he is alright. I'd hate to hear if anything bad happened to him with all that is going down in Iran at the moment.
I thought the same as well, but occasionally he just watches from the cheap seats (as I do sometimes).
Like many members, he takes breaks and lurks the threads from time to time. Glad to see this is just another break, and not something else.
