A pinned post with a Typeform or Jotform could work. There might be some better options though so I'm curious to see what others say.

It would be nice to ask questions in a community like this but it still doesn't feel like the safest space for me - it's too public. Calls that were not recorded would be fine. Or maybe some way of posting anonymous questions? Like you could have a pinned post with a link to ask questions anonymously? Maybe even encourage pseudonyms if people want to create alternative personalities here to remain semi-anonymous? I can see public posts working with people who are already an open book sexually, but for those who aren't, they may be reluctant to talk. Just some ideas! :)
