Hello, I have been using Dokuwiki for many, many years and developed a site (currently under re-do and I will tell you why later):
http://www.rsywx.com
My name is Taylor Ren (aka TR@SOE). I live in Suzhou, Jiangsu, China. It is a very nice place.
I am currently self-employed, doing translation (English - Chinese), doing website development, etc.
Previously, I used Doku and MarkDown Extra, MathJAX.
The issue I have is that the MarkDown Extra plugin is not stable:
1. Created a page, say "01.01.md.txt", and write with MD Extra features (table, footnote, in particular).
2. Preview, Save and display OK.
3. Surfing to other places in the same wiki and return to that page again (not by "back" but by clicking the wiki links in breadcrumb or link in another page)
4. Sometimes, the MD page will be displayed as plain text.
5. Reload is no use.
6. Edit the page (change anything) and then the MD effect is back.
So, now I am re-writing everything with DokuWiki syntax. Luckily, it is still manageable.
Anyway, glad to have this great tool running. And as other threads mention, it is really cool if we can have built-in MD Extra support!
