You can contact Hemant by sending an email to mpromptu [at] gmail [dot] com. Any email that is sent to him may be reprinted (in part or in full), in any format along with the sender’s information — URL, email, IP address. (So don’t be evil.)
A lot of emails and link submissions are sent to this site each day. If Hemant doesn’t respond, rest assured he did read the email and check out the link, but for whatever reason, he chose not to write about the subject. Don’t take it hard! And please keep sending along those suggestions.
For some reason, links do not always show up in the email! If you’re sending a link, a description of what you’re sending including a quotation, source, etc. is always helpful.
