Thanks for your answer, slimvirgin.
On what other websites has this been discussed? More crucially, has anything come of it (at least so far) by way of an attack?
One thought of mine as to why their 'putsch' has not (apparently) occurred is that the conversation was an old one, and that this charge by WhiteBamboo and co has not (apparently) taken place is that they changed their minds for whatever reason. Perhaps it was a bluff, as suggested by others.
But if it was as recent as Feb 2, well, I can certainly understand the concern of wikipedians on Feb 6, which is when this topic was first raised.
