After I volunteered to manage our blog, I've put together a spreadsheet* that includes a list of users that said they'd be willing to participate in the blog in some form, plus additional information about specifically what they'd be willing to do. It also includes a draft of the schedule, on a second sheet.
The idea behind the schedule is that we will follow it (for four weeks, as of now), and then start again. The fourth entry is for anyone who said that they would contribute, but not regularly. The idea is that at first, we will roll with a three-week calendar cycle (dropping the unspecified person), until we accumulate some drafts that we can start publishing when the fourth slot rolls around. At that point, we'll switch to the four-week calendar cycle. Make sense, ish?
Every cycle, you will be paired with an editor. In the spreadsheet's draft schedule, every writer is paired with the same editor every cycle, but I'll probably switch it up every cycle in the final schedule.
Depending on if anyone else says that they'd be interested, you may write less frequently.
Answer or comment if you have any objections. The spreadsheet is editable to the public, so if something isn't right with the users list (or if you aren't listed and wish to be), just go ahead and edit it.
*Yes, I know it's Google. Centralized, data-sucking, proprietary Google. Not all of us have our own ownCloud instances (yet), though; if you object on ethical grounds and have an alternative, hit me up with it.
