For the past few months I have been using PSPad as my primary text editor program. Most of the time I use it for writing PHP code, along with HTML, JavaScript, and other text files. PSPad is a free text editor with syntax coloring for many languages. It also has a code explorer, which is very handy for jumping to sections of your code. There is a color picker that makes hex color codes, spell check, an FTP client, project management, and other useful features. I would love to see a code indenting feature.

On the PSPad website (http://www.pspad.com), there are forums. I check the beta forum often, where beta versions are released usually every few days. I enjoy trying new versions and reading about what new features/bug fixes there are.

Previously, I was using PHP Designer 2005 most of the time, but since it has had a period of no new releases, I decided to check out PSPad. PSPad is a little faster and doesn't have visual glitches. I used to use HTML-kit most of the time, but the program hasn't been updated from build 292 in ages. It does have great plug-in support, however. I just read that a new plugoms interface is in development.
