Yeah the registration itself was easy like any other site, I was talking more about grasping and understanding the concept of instances and how they interact.

And as someone said in another comment, the see all posts options should be the default in your home and community search or you feel like in a dessert island when you are new to all of this.

I sent my registration yesterday, because I signed in another instance, one from my country, but I couldn't see all the post and no comments from lemmy.ml even thought is supposedly linked, so thank you for approving my account.

Even if I'm a tech savvy person I found the whole experience of joining lemmy pretty bad, I like the concept of federation, but I think it's too confusing to normal people, it really needs to be more seamless if you want to grow, how? idk, I was thinking some sort of replication, when you sign up, you are registered to the main instance (this) and given the choice to select other instances, automatically selecting let's say another 3 based on your location, then your account is synced in all the registered and linked instances, when you login if an instance is experiencing overload then it switches to another one. I don't know if this is realistic or out of the scope of Lemmy, or maybe against the philosophy of it. I'm just rambling.

I'm just glad that there is an open alternative for anonymous social interaction in this day of walled internet services such as discord, twitter, facebook etc. and I wish you all the success.
