When you lost an ID that you enjoy a lot, you don’t want to use that site any more. It is the case for me on SJTU BBS (Shanghai Jiaotong University Bulletin Board System). I started to use it when I was a junior there. I used a nick name stonebook for few years, before it was terminated on Oct 26, 2003.
Besides Facekbook.com/jianshuo, you can private message me @jianshuo on SJTU BBS now, if you have a nickname there.
