The cafe is closed, but at least there will be an online refuge for “Rent” fanatics. Owner Kathy Kirkpatrick announced yesterday on Life Cafe’s Facebook page that she is nearing a “soft launch” for Rentheadregisters.com, a digital version of the tomes full of the signatures of “Rent” fanatics who made a pilgrimage to the restaurant where the musical was written. “An estimated 10,000 ‘Rent’ and Life Cafe fans left messages in these books. We will eventually have all the pages scanned and available to read on the site,” Ms. Kirkpatrick wrote.
