A camera is not necessary, but helpful. Without the camera your beautiful face will not be seen by the chatters. Otherwise the forum is a live type-chat. I guess you/we could use mics and have a live voice-chat, but these are posswibilities. I encourage everyone to check out this new, real time, interactive forum.
Again, let me say that this is not a replacement for or competition to SZ. There is only one SZ!
