Update Blog today after the program, suddenly found that the PR bar on Google Toolbar added a little, but has been the Google Toolbar on the PR because of the buffering problem, so that the current display of the PR value is not necessarily the current page of the PR value, so go check, find blog site (http:// mlsx.xplore.cn/) PR value rose to 3, but the home page (http://mlsx.xplore.cn) or 2. Rattling, celebrate.
But Glemir this morning told me his blog has been to 3, so I am a little jealous, and think of Rachel's blog, they update are not my diligent, but their PR basically do not need my poor. I have come to the conclusion of two personal comforts:
1 Rachel's PR is the same as mine, because his travel log is popular, I do not have his handwriting.
2 Glemir PR rose faster than mine, that is because he used a good blog program--wordpress
Haha, laugh at yourself.
To get to the point, posted on Google's PR value code, the statement is not I wrote, but modified, checksum algorithm for the time being not known.
