One good thing of word press is that it has support for plugins. Plugins are script written by others that can enhance the functionality of word press.
Here are some useful plugins:
Keyword plugin: this plugin inserts meta keyword tag for every post.
Adsense plugin: this plugin helps do adsense easily.
Originally I was looking for a spell checker plugin for word press 2.0. Seems no such plugin yet.
Then I tried the spell checking feature in the google toolbar. Seems it can meet my requirement too.
Following is the snapshot of spell checking by google toolbar. It is interesting to see Google doesn’t add “google” as a word in their spell checker.
