Creating macro that will submit email address on a website

Hi everyone,

I'm new to this forum so let me know if I am doing anything wrong.

I'm referring to websites that have the "enter your email address" and then have a submit button.

I want users to be able to enter their details into Excel, and the macro will automatically submit the email address for them (ie go on the website, enter the email and submit it - preferably in the background so it doesn't deter from the usability of the excel form. I can't get past the stage of opening up the website via a hyperlink.

Any help would be great! Also, if it is not possible please let me know.

Thanks,
Thomas
