This is the categories page for OpenWetWare. We use categories like tags. For instance, DNA ligation would be tagged with the categories: Category:Protocol, Category:In vitro and Category:DNA. The advantage is that you can add articles to multiple categories by simply typing:
[[Category:foo]] where foo is the category name
The category pages are then updated automatically to include the article in alphabetical order. Note that categories can be added fairly easily after articles are written. To point to a category in an article without making the article fall into that category use:
[[:Category:foo]] where foo is the category name, note ':' in front of Category
Here are some commonly used categories
Special:Categories <-- all categories. Contains many unused or underused categories.
