I'm looking for a very simple online tool to manage a small Web site project. I'm currently using a Google doc to keep track of everything, but there has to be the equivalent of a project Extranet - but much smaller. I would say Basecamp, but modeled more towards actual Web projects - so something styled towards the 'define, design, develop and deploy' workflow of building sites/apps that doesn't cost a lot. I'm not a huge fan of Basecamp, so I'm interested to find out what people use with clients.
More details/requirements:
- to do list: calendar is less of a priority, but that to do list is a big part of what I'm looking for, and the ability to have categories and dependencies without getting into a Gantt chart or schedule
- cost: ideally free or low cost (less than $20/month) - part of the reason why I'm not going to use Basecamp is that I can't justify the cost for such a small project for a small client
- hosted: don't want to download anything and self-host, and don't need a specific app - a SaaS Web based solution is fine
- collaborative: could be shared with another person (the client) privately
- mood board: some sort of ability to have a visual repository of inspirations or links. This is a minor thing - I can just use Pinterest for that.
At this point, I'm not tackling the development part, but if there were checklists of things to start thinking about, that would be helpful too to have built in, although I know that's not likely to be prepopulated. I like something like the Business Model Canvas (http://www.businessmodelgeneration.com) that forces you to think about the things you need for a successful product, but again, I probably won't find that in a project management tool. I've tried Trello and Evernote, but they aren't Extranets. I love Central Desktop and various wikis, but again, I'm looking for classic Extranet tools - task lists, places to upload a document, have folders for drafts, etc.
Thanks for your help!
