FOSS gamedev and creative worlds

I don't know whether its just for me but the poll on the first post of this topic ----> https://forum.minetest.net/viewtopic.php?id=7593 keeps disappearing and it only comes back when i have logged in. Is this so only registered people can answer?
Also is there any way I can edit the poll once I have posted it?

If guests could vote, it would be kinda unrealistic/spammy.
And you can't edit your polls...sadly.
