As you noticed, openwsman.org has a new look. The old content is still available but will be removed once everything has been migrated to the new site. Old content can be accessed via http://trac.openwsman.org. Some features of the old site are still accessible from here, for example the timeline, the source browser and other great trac features.
If you had an account on the old site, you will need to create a new one here. If you had privilleged access let me know so we can restore your permissions and give you the right acccess.
