Dear Sister,

It sound to me like your household needs a computer schedule. This is, quite simply, a written schedule of who gets to use the computer, at what time of day, and for how long. Anyone can use their computer time for whatever they want - homework, gaming, surfing Myjellybean, whatever - but once their time is up, they have to get off and cede the machine to whoever's name is on the schedule for the next time-slot.

Suggest this to your parents, and offer to prepare a schedule for the family. Consult with everyone, and make sure the times you put on the schedule work for them. You'll want to make sure it's fair too - everyone should get equal time - and the times allotted must be enough for the important stuff (like homework) to be fit in. Once you've made up the schedule, ask for family meeting where you all sit down together and look at it one last time, before you all agree to stick by it.

You might also want to come up with "penalties" for violating the terms of the schedule, as well. Make sure your parents sign onto these. If the rules have consequences that your parents actually enforce, it will provide your brother - and everyone - much more motivation to stick to them. For instance, if your brother violates his two-hour time-slot on Tuesday by hogging the computer for a four-hour gaming marathon, your parents will impose a specific punishment (like not letting him use the car on Saturday, or whatever).
