Nono you’re all good, it’s the first time for a lot of creators here )myself included) so whether or not it’s your first time or just need a refresher it’s totally fine.
Firstly, yes and no. If you want to participate (it’s an optional event) you do have to make an announcement on April 11 (according to the instructions) with an episode whose content is the announcement template they put together (you can download it) or your own version of the announcement template. During this same episode post, you can also announce some activities or rewards that your subscribers can participate in if the ink amount donated to you is a certain number or if the person had donated a certain amount. This is just to stimulate the ink donations from your subscribers. Again, if you don’t want to you don’t have to do this part either, you can simply post the announcement if you like.
In regards to the hashtag, according to the instructions, you can use them in your posts (it was unclear whether it applied to all tapas platforms only or anywhere else, if you need to please verify with tapas support or a moderator) for a chance to have tapas repost it as an official tapas post. This is optional as well.
