I am happy to report that Lotus Component Designer 6 is ready for your beta testing. This is the product formally known as Workplace Designer - it didn't make sense any more to call it Workplace Designer, even though I liked that name, because now it supports deployment to WebSphere Portal and eventually will include support for Lotus Expeditor and the Hannover/Notes client.
There are lots of really cool features in this product, so I hope you will give it a try. I'll blog about some of them in future posts.
The developerWorks Workplace page leads to the download site.
