HI shivanagi,

kindly reconsider you request to close the thread. Your sudden request seems to imply that you are unhappy/ annoyed with something in the thread.

In case it is due to your inability to devote sufficient time, it is still great service from even if you post not so often.

This thread is simply too good to be closed thus.

I have one more request from shivanagi and other members ( in case shivangai is constrained for time ) to discuss the afl in more depth.

Regards
