For personal activity logs, !ObsidianMD@lemmy.world with a synced folder. It could probably work for a team too.

If you make a post and tag @fediverse@lemmy.world it should post the first line as the title. If you include a link, I think it will post it as a link too.

Edit: found the issue, it looks like links aren’t supported but it uses the first part of a post as the title.

IIRC the post format is:

Title
@community@server
Body text
