Advice On Recurring Ranked Voting Software

At my workplace we have an educational meeting once every week. Anyone can suggest a topic and at the end of every meeting we do a ranked vote on next weeks topic.

Do you have any suggestion on software we could use to simplify this process?

I am looking for the following features:

• View available topic suggestions
• Add new topic suggestion
• Remove topic suggestion
• Start a ranked vote on the available suggestions (normal vote is OK as well, but ranked is strongly preferred)

It would be extra good if topics availability could be toggled on/off for voting in the case that the person who suggested the topic would not be available to hold the meeting next week, but the topic should still remain as a suggestion. But we can manage without this.

All I am looking for is a low friction available way to set this up and use it once a week. If anyone comes up with at new topic suggestion it should be very simple to just add it to the pool and go back to what you were doing.

I appreciate any advice.
