It would be nice to have a better way to Version knowledge base articles.
Currently what I end up doing is going to the article in question:
1. Create a blank article in the default category in a folder containing the different versions.
2. Go to the article in question. Copy the article's contents.
3. Paste the contents into the new blank article.
4. Either edit current article or paste in a brand new article.
Generally I have to archive (I will need more than 3 level hierarchy to store them in the default folder.) or edit them using a different program.
An import and or copy function in the knowledge base would be greatly appreciated.
