z/VSE Blog outage resolved

Some of you may have noticed that my z/VSE Blog was temporarily broken and did not list any entries. This has been resolved.

While at it the IBM Community team has also improved the formatting of my blog. Each post is now displayed with a lead-in.

Please note that during the outage all entries were still available in the z/VSE Topic Group, which you can reach from the top navigation menu by hovering with the mouse over "Topic groups", "IBM Z", "OS", and then clicking on "z/VSE".

I greatly appreciate your feedback via the z/VSE contact form.
