Due to the problem arising from too much information being the same as that in Wiki48/Stage48 (which I apologized for: User_blog:Sijfer/About_Wiki48/Stage48) I would like to protect the pages from outsiders, so that only the ones who are logged-in can edit the pages. This is to block anyone that isn't logged-in (even me, if I forgot to log-in) from editting the pages and erasing them, just like what happened to 3 of the pages. One of them is AKB48 Group Rinji Soukai "Shirokuro tsukeyou janai ka!", which was recently attacked by a person only known by his I.P. number 188.8.131.52, possibly claiming to be a member of Stage48, left the message: "Stop copying Wiki48 pages". The message can be clearly seen in the page's History Section. To my fellow contributors to this Wiki, I humbly apologize for this, and for the new users, make sure to contact me through my wall (Message_Wall:Sijfer) if you can't access/edit the page you want to contribute, and I apologize for that.
The other 2 pages that were attacked were AKB48 2013 Summer Dome Tour ~Mada Mada Yaranakya Ikenai Koto ga Aru~ and AKB48 Group Kenkyuusei Concert ~Oshimen Hayai Mono Gachi~, in which I have left an apology in the latter page. So, again, to those who will be inconvenient by my action, I apologize.
