Hello,Good day all time ,my have a advise that we can seen
e-mail address at the forum.If done this ,our communion become very easy.

No it doesn't. This forum has tens of thousands users. If two hundred of them have the same question, the first one can ask the question in the forum and most of the other 199 people can also read the answer. With your suggestion all two hundred send email. That does not work.

That is why we have a rule against email communication. When we help a person via email, we help only that person. When we help a person in the forum, we also help hundreds more people.

I realize that having a private expert who did nothing but answer your email would be more convienent for you. But it's not realistic to expect a service like that for free.

Also, NOT having email addresses in the forums prevent spammers from harvesting the forums for email addresses.

Perderabo was right on target on the primary reason we don't use email addresses or private messaging.

I have more think with your a sentence." we help a person in the forum, we also help hundreds more people"
