Warning, don't read these New Age posts unless you are secure in your faith...

Dear Ones as you are learning from a number of sources, the point has been reached when Divine instructions have been given that action shall be taken without delay to announce our presence. We have shown extreme patience and given your leaders plenty of opportunity to take the steps called for to release you from the control of the Illuminati. We know that they too are also like many people in fear of them, but that has to be put aside to allow the truth to come out. The Olympics is the window that is being given world attention, and we cannot think of a better way to make it known. Time is fast running away and we must be given the opportunity to make ourselves known to you.

...

I am SaLuSa from Sirius, and many of you will know already that this coming week is one that is a last chance for your leaders to respond to our demands. If we are ignored yet again, we shall go forward ourselves, and make ourselves known in such a way that our presence can no longer be ignored or hidden. Yes, we have the deadline Saturday the 4th. of August in mind and no longer, before we take matters into our own hands.

However, keep in mind, that they've promised to appear MANY times before.  Still, having monitored these communications since the Blossom Goodchild incident (10-14-08), they talk much more about their appearance around the Feasts of the Lord, esp. Rosh Hashanna and Pentecost.   It is rare that they mention dates.

OTOH, it is possible that they don't know the time either, and are monitoring us for clues.  They know God is most likely to act on the appointed times and in Biblical patterns. 

We Christians apparently harbour the old ways and deprecated beliefs, and will be wisped away for further training until our beliefs evolve.  Or so they say...

Still, don't take these liars as a serious/reliable factor for high rapture watch dates...
