I hope WordPress and Mediawiki could have almost the same appearance, while it's too hard to find a perfect one.
Now I can not spend too much time on this issue, and the current one is acceptable for me, so I'll not focus on it.
I tried to share my great idea with my wife, while she said she just wanted me to pass the English test.
I'm not satisfied with the performance of the wiki pages, so this is the next issue I'll fix, and plan it in the end of next January.
Oh, I forgot to mention the Mediawiki had been integrated in my site, and the SSO should work.
After the English test, I'll begin to devote myself to the learning of new Oracle12c, and will update my wiki pages frequently.
