True, didn’t think it that way. I don’t know what would be best, English is such a wierd language.

I think in combination with “The Sunday thread” it’s unambiguous?

Perhaps, though I guess it could also be that there is “The Sunday thread” and “The Wednesday thread”.

As for whether fortnightly is common or not, I think it is, but the other commenter suggests that only the Brits use the term. Fairly certain I’ve heard that from an Aussie friend though, could be that US Americans don’t use the term.

Perhaps semimonthly is the most unambiguous term? That’s what Mariam-Webster seems to suggest.

I feel bi-weekly is a good rhythm for this.

What does biweekly mean to you? Twice a week, or once every two weeks? If it’s the latter, I prefer to use fortnightly, since it’s not ambiguous.
