Content Tools

As I set up my business, I come across tools I find useful. Perhaps you are looking for things like this as well:

Dokuwiki Wiki system: I like the idea of a place where I can store information that is beyond a file service (hint to Dropbox et al - offer this type of application to put structure around files ). This is a personal place to capture “stuff”. This page you are looking at is part of my wiki and uses Dokuwiki. This site is built using DokuWiki.
Pipe Drive: Simple customer relationship management (CRM) system based on Kanban style cards.
