※ This post is written before the blog is running in multi language mode. So captured images are consist of English menu and Korean contents.
No one (including me) remembered that when I made this blog, I wrote that ‘wordpress have many functions, so I will install and using here as not only blog’. Among the many features of wordpress, I was interested in wikipedia function. After searching, I judged as ‘wordpress has wikipedia function using plugin. But it is not easy to use and have many limitation.‘
After disappointed to wiki plugin, I forgot it and several months passed after then. Most of all, I couldn’t use blog function itself. I have no capability to use other feature. Recently, I had a chance to search and test mediawiki program in the office. And I try to make my own page. (It is not based on plugin. I think that function is not so important to me.)
As a result,

the blog changed from above to …

Like this.
My blog changed to simpler and use less color, and the most important change is small text in the top-right of blog. Can you see the text ‘Wiki’? There are some trial and error to make my own system. It is not wiki exactly, but the appearance is similar to the wiki. To see ‘navagation menu’ which is not seen in Blogvi theme, I changed to Twenty Twenty-Three theme. So the blog skin is changed to much simpler.
During changing the theme, I recognized that wordpress can use featured image. (I prefer to call as thumbnail image) If the post doesn’t have featured image, The appearance in the Twenty Twenty-Three theme get very ugly. So I adopt every posts havefeatured image.

Blogvi theme also get more beautiful when the featured image is adopted.
After several days.. I fixed many items and weak point of Blogvi theme can be improved if I put more effort into blog post. But weak point of Twenty Twenty-Three theme is hard to improve.
For example, The width of Post or Page is very narrow.

Just like above. I can’t use blog’s space. My former blog tools change change content width, but I can’t the way in wordpress blog. So I determine return to Blogvi theme. And I edit featured image again adjusted to Blogvi theme. At the first time, I think ‘I will just add the wiki page’ but there are many operations following add page operations. Managing blog is not easy. 🙂
