@tinabing,
Tina, are you still around?
You ask: : "I have tried, but have no answer received. Do the people behind this page exist?"
It seems that there are very few folks working here on a volunteer basis, so they are very busy.
I myself am trying to contact them, but in vain: for not even when I got to post as in a group of posters wanting to contact them, I don't get no reaction from them at all.
Still it seems they talk among themselves, but too busy to deal with our inquiries or say gripes.
But, I tell you, these chaps are pretty tolerant, you don't get banned easily, just suspended.
And to date I have not been suspended, except I got two threads I started and they went into limbo, no sight of them soon after they came out in public forums.
And I can't imagine why they put them down, unless it is because the threads have titles which they don't like, for example, in the first thread I titled the thread like, Dear name of poster I really want to have an exchange with you one on one on how to think.
In the second one, the title of my thread was "The Complete Philosophy Best For Mankind," the idea there is that all thinkers who start with nothingness as their launching pad, they should be avoided like the plague, because they are in effect crazy, for how can you at all start with nothing-ness, for it already requires that you also evaporate into nothing-ness - unless these nothingness guys are just liars to themselves and hope to deceive us also.
So, you see, I have experienced two threads I started, and they came out, then later I checked and they were gone, out of sight in the public forums - that means there are guys working to control how we contribute thoughts in their a2k forum.
So, I say to myself, I am having a good deal here, no need to antagonize the chaps running the show here, they ain't no characters like atheists in their own atheists' forums, these latter guys are a nasty lot: unless you really have the stomach, like you have to study their nasty psychology, better steer clear of these nasty very nasty forums.
