Hi Gordon,

Maybe I have not properly understood LVQ. I thought that LVQ allows to 
read messages in reverse order. It is a nice feature to have, so that we 
will be able to read the most recent messages in the first place.

Best Regards,
Sergey Zhemzhitsky

I'm not sure I understand the question, could you elaborate a little?

Yes to the first part, no to the second (as for question 3 above)
