I use bank sites ,ISC, some newspaper web sites and some other sites frequently. I see changes in them now and then.
Actually instead of feeling happy , I always feel scared when changes occur without notice. This especially true for me when I have to login with password and have some personal details i those sites.When I notice a visible change in the interactive page of a site, I doubt whether it is genuine or I am a victim of phishing or virus.
So I suggest that let there be some intimation before some such changes are taking place.
I get tense when I get stuck up after keying i password to the sites for some transaction or login. It happened to me in some cases and I was very tense. Then I had to run the security scan, cleaning etc. But when everything was okay, I sent an email to the site and confirmed that everything was okay and genuine and there was a big change in the site page and some updating.
They could have given the intimation by secure communication method. No all reply even to specific email also.
So I suggest ISC also to announce such changes.
