Well there's a serious privacy issue there, in revealing to you what a third party has or has not done.

I don't see the privacy issue here.
Why would I as receiver need to disguise to a sender that I have read or not yet read the message sent by him?

This receivers read status display to the sender is common in many CMS systems that have a PM module as eg XOOPS.

Tom's point is that this isn't a technical issue, but a community one. If the majority of the community are happy for this to happen, the code could be written, but it's not something that should be done because one or a few people want it.

Start by asking the question on the Talk mailing list, and take it from there.

@Ghia: I strongly oppose that suggestion for privacy reasons. I would not like to give everybody the option to see if and when I read a message he sent to me. Your suggestion is no usual message system behaviour (e.g. the email client Mozilla Thunderbird blocks tracking attempts by external image inclusion in mails by default). If you want to know if a message has been read, just ask the receiver for a short confirmation reply.

Thank you for your feature suggestion. However, we don't intend to implement it, so I'm going to close this ticket.
