As shown on the “History of Mass++” page, the domain “masspp.jp” had been used as for the Mass++ ver.1 publicity page, which has not been maintained since April 2012.

Now the ownership of this domain is transferred to us, the Mass++ Users Group, and we configured the access to http://masspp.jp/ for the automatic redirection to https://mspp.ninja/. This redirection will be maintained for the time being, but don’t forget to update your hyperlinks and/or bookmarks to https://mspp.ninja/.
