As a computer enthusiast, I am signing up in many websites using my email address for software downloads, discussion forums, reviews etc… Many times it is just to get a confirmation mail or an activation link from these sites which I will never use after that. Who knows what will happen to my email ID that I am submitting to these websites… some share the same with spammers for extra money.
I just came across a website called 10MinuteMail.
This website gives you an email address with just a single click ( believe me, you do not have to fill up another registration form ! ) and it remains active for the next 10 minutes. You are able to read,delete & reply to the mails you get. If you need more time, you can request for that too…
What else I could ask for?… I am now much relaxed that I do not have to share my email address with possible spammers. Do check it out…You will not be disappointed. 
That sounds really cool! But for only 10 minutes? I need it atleast for an hour or so. Atleast to get a reply from a mail I send from there.
@Jo -> You can extend the time …. default is 10 minutes…. just check it out!
slashdot. Appears on 28 and you post it the very next day
@blah -> Yes. Definitely Slashdot. I thought I would share it with everyone I know.
