Made myself an Imatsubu account, which is a twitter-like website made by Fuji TV. If you've already got a Fuji TV account, you can use that to make an account. (I already got one since I joined Idoling fan club ;p).
It can also connect with twitter, so that your imatsubu posts are also posted on your twitter.
I made an account because recently Fuji TV has made accounts for all Idoling members.
