I had forgotten about this but The Teacher of Bray and some stumbling around in the blog brought it to mind and it seems worth re-raising. A few years ago I offered for people to write guest posts for this blog. No one took me up on it, not counting re-publishings, but perhaps someone is now interested. Below is what I wrote a few years ago and, modulo a couple very minor edits, seems fine to leave as is.
*********************************************
From time to time, I’ve had guest posts on this blog: a number by Tony Gardiner and see also here, here, here, here and here. More accurately, these guest posts were pre-written articles that the authors agreed to be republished on the blog. In any case, I’m happy to contemplate more such posts, pre-written or otherwise, and I’m now inviting readers to consider this.
In general, I’d hope to be very non-censorious when it comes to accepting such submissions, and to be non-editorial except by request. So, for example, if someone believes that they have a brilliant How CAS Saved Victoria’s Mathematics Education article in them, I am, by default, more than happy to publish it. And, if someone is confident their writing is beautifully brilliant, and is not seeking my proofreading or advice, then that is also fine.
In summary, I’m happy to consider posting any article within the broad themes of this blog, with the understanding that it is your neck.
Also, a warning. I don’t think my writing on this blog, or elsewhere, is anything like great, but it is generally serviceable and it is mighty tough to accomplish even that. Writing well is really hard work.
