be clear about how much organisations need to donate to Dandelion#298

Be clear about how much organisers need to donate to Dandelion to have their events listed on the main page. It was mentioned once and now I can’t find any mention of it anywhere on the website and my events have been removed from the listings page. I want to enage with this platform but the finer details and T&C are easy to find. This should be liusted in the how to create an event page as it’s rather imprtant for new facilitators that aren’t anything to do with the Psychadelic Society
