Any website that implements ActivityPub APIs properly can federate with other sites as part of the fediverse.
In the light of the above ☝️ statement and in the context of the given lemmy post, l am presenting three websites as an example :
Can such websites be created and made to federate as a part of the fediverse ?
In this regard, l would say that you don’t need to haggle to register for a domain name like you have to do for a website having a .com or .org or .net extension.
Is it possible to create email ids for such instances to which mails can be easily sent from gmail or Yahoo mail or any other normal email address ?
