There is the Splinterlands Discord where we all hang out: https://discord.gg/BYgvzHe
Writing Splinterlands content is pretty much the only way to earn SPT at the moment, which includes comments as well. You can do fanart, guides, analysis of cards and Splinterlands tokens, financial posts about Splinterlands ecosystem, do the weekly battle challenge from Splinterlands and post your battles and so on. Don't do boring stuff like sharing a screenshot from your rewards with one sentence and expect any upvotes. Only when the post shows some effort and is somehow interesting/relevant for the Splinterlands community, you will get an upvote. Check out the trending page to get an idea what we are looking for.
Hoy por primera vez publique un fanart y no sabía que existía esto. Espero aprender más porque me gustaría seguir creando personajes basándome en el original. Saludos y muchos éxitos en este proyecto.
