I am looking for exactly the same thing for my site https://www.topukbargains.com I would like people to subscribe and post their own finds but so far havn’t been able to find anything.
Please let us know if any of you find anything.
Not sure if you can edit it on your current theme but I have seen a few themes with a welcome message column already built in them, so you might be able to find one which fulfils your requirements and comes with a top column.
