Craig,
Natuarally I have had done these many times during last 4/5 weeks.However I did it just now as you say. Please note I had to toggle it because my account showed subscribe button already selected.
Craig these had happened to me long back and I complained as usual but in vain.In recent past it never happened to me.As far as I remember there was no problem even after I changed my email id from vsnl.net to hotmail.com.Trouble started when I had to shift from where I was living.Since I was busy I thought to unsubscribe for a few days.After I am set in my new residence I can no more get your mailing list.
Please look after it and do the needfull.
Thanking you
A.S.Rudra
