I’ve been using yahoo email for a great while, I guess ever since yahoo went public. In additional I’ve also been using Yahoo Calendar as well, over years yahoo improves its services such as Yahoo email plus and also enhanced its calendar. What I use yahoo calendar are, schedule certain task to occur at certain time and date and send me a text message or IM chat message or email notification, on cell phone text sms mms instant message. It’s pretty cool, kind of remind me what to do and so on. Now a day many people have many things to do running errands and stuff, with technology mayb people saids it’s making us lazier I have to disagree with that, most people like, have many things to do, many things to remember, so this tool help me greatly to schedule meeting, pay bills, reminders of certain tasks, and so on. I don’t believe it’s currently encrypted, but none of mine stuff are confidential anyways. If you want secure, you can try google gmail it also has calendar and probably better one faster, but I got use to yahoo already and haven’t been able to find a reason to move to gmail google calendar yet 🙂 Remember to use comment sense when accessing your account, always type in the browser gmail.com or mail.yahoo.com to access your account, don’t click on bookmark or links notify via email or something … be safe!
