I have written an earlier post on this subject: eMail Contact Form for Blogger (click BACK button to get back to this page), but the site that offered the contact form required me to download a program, which I was reluctant to do. In that post Amit suggested another alternative - Contactify where you don't have to download any program, but you will have to divulge your email address as well as the password. I was not willing to do this for my normal email address, so I created a new gmail address to test it out. I have in this way created a way for the blog visitors of Blogger Articles to contact me (at the new gmail address) without having to reveal that email address. The "email me" link to the contact form is at the bottom of the left sidebar of the above blog. Try it out, click on it and see what is the result. (Note: turned out that the password to to log into Contactify, and not the password to sign into your email Inbox).
Update 28 April 2007: Shawn of Stock Blog Hub commented you don't need to give the password to your email address, but an email address to log into Contactify. I tested that by creating a gmail address, register with Contactify and gave my email address plus a password different from the gmail address to create the link. I copied the link, click a Add a Page Element and selected Link List to create a link to the Contactify contact form. You can see the link at the bottom of the left sidebar of the blog Career and You. Try clicking on that link and see what happens. I did that and found the responses were instantaneous.
