Halfhaven is a virtual blogger camp, an online alternative to Inkhaven Residency.

The rules are simple:

every day post max 1 article with min 500 words (or equivalent effort)
try to get 30 by the end of November (but there are no hard lines)

The invitation links keep expiring, the current one is: https://discord.gg/rZv3a2Jt

If you wanted to join during November, but you couldn't join because you didn't have the link, I apologize; I was on a vacation without internet. If you published your articles online anyway, feel free to add them retroactively in Halfhaven with their actual publication date. In general, post a link in Halfhaven the same day you publish the post.

Here are the posts published during October:

Feel free to join anytime. If you join later than November 1st, you won't be able to achieve the soft goal of 30 total articles before the end of November, but a few articles is still more than nothing, if you need the nudge.

Congratulations to: Algon, keltan, mishka, and Taylor G. Lunt -- guessing by your productivity so far, you are most likely to have the 30 posts before the end of November. But nothing is certain until you actually do it, and the rest of us may still have a chance.
