I Want to Make a Writing Site

What you're asking is potentially very complex. The simplest route is to use a simple multi-user posting system - such as a forum - to allow people to post jobs or whatever. Then you'd do all the leg-work of assigning tasks and so on, which would be a LOT of work. The alternative is to create an interactive site, as you suggested. However, to do that you'll need to either build it yourself or have it built. If you build it yourself, you'll have to teach yourself a CMS or a coding language such as php. If you have it built, you'll have to pay a developer. In either case, you'll need to design the system before it's built. That's an entirely different skill-set, based around requirements gathering, conceptual modelling, writing specifications and - above all - considering all the possibilities for use/abuse of the system so that it makes sense. If you decide to pay a developer to do the job, you're looking at a fairly large investment, especially if you don't do the designing yourself (since you'd need two separate professionals with different skills). The same goes for a fanfic site: you could push a pre-built system to do the job or you can have one built (or build it yourself). Obviously, using pre-built systems limits what you can do, how easy it is to use and so on. From personal experience (I have a rev share site, PenStars, just about to go into beta), the development costs will be well over $1,000 for a basic automated setup. They could easily be twice (or even five times) as much. I did all the design work for my site myself, since I have a background in IT which includes process modelling, requirements, testing and a lot of the other ins and outs of development work. I have about 35 pages of text, diagrams, flowcharts and other info that is (according to the dev I'm paying) unusually well-prepared for most projects... and that's the only reason my setup costs are at the lower end. Even so, by the time it hits beta, I'll be well over $1k out of pocket. If you cant do the system design yourself (processes, not colour choices), you're looking at another grand or two for someone with the required skills. All in all, for a basic automated system that you have designed and built for you, I'd say you'd need about $5,000 to invest. Just the site dev, $1,000 to $2,000 (depending on complexity and framework). For a truly professional setup, double or triple those costs. Oh, and you'll need hosting, too. Once you hit more than a few users, that means a VPS which is another couple of hundred bucks - at least - per year.

I had some days back inquired about the possibility of having such a writing site. Even then it was Spike who had given some good answers and guidance. It's another thing that my other engagements and the lack of time has not allowed me to give my full attention to my ambition of having one such site. But I am always in the hunt to do it. Anyways, good luck to your project and remember, I will be a writer there too
