You can buy the ingredients in shops (apothecary for example) or you can win them at the whispering wizard (:

You have to be level 5 or higher to write a topic, because often troll accounts use topics to bring chaos to the sites (creating an account, posting random (or insulting) things in topics, or posting uncountable topics in a short time). By having to be level 5 this is not possible. Also, many people who are new to the wolrd of rpg need some time to get used to its principles and rules before they can start their own topics, which they can do until they are level 5. 

If you have an idea for a topic you would like to start, you can always message someone from the staff of your site or a prefect, they can open the topic for you to write in (: 

Hey, thank you for your idea. Please suggest it to the MoM of your site, as they are the ones that can add new emojis (: 

Are you still a canary or are you back to normal again?
