Thanks Jimmy,

I have been looking for some sample script for ages at every possible
place. So, far no luck but its really nice of you to post your script
here. I always wondered with open source software what is the deal of
posting your functional script (hiding your confidential info) but
never had an answer. Finally I see a brave person posting script...

Would you mind if i try your script and see if it works for me???


Thanks,
