I don't use the private messaging facility and think that overall it is better this way.
TA is meant to be a public forum and if what one wants to say (to strangers, after all) is not suitable to be read by the public then perhaps it should not be said at all.
And anyway, I was surprised to discover that ones' private messages are not, in fact private but can be (and are) read by TA whenever they wish.
I am discomfitted to read how some "friendships" are developing privately, people are swapping personal email adresses and getting sucked into relationships that are based on falsehoods.
We all know to warn our children not to give out personal information to strangers one meets in chatrooms, but it is of concern to me that some people are not wise enough to take that advice for themselves.
PS. There are so many thoughts and concerns I have but am unable to voice....eg is there internet access during flights from USA to UK....?
