Yes, bc 1 famous SC1 community now is Discord and there are clans out there, but depending on your luck, you might find the admins/mods of these clans are nice people, or just tyrants/trolls, bc the rules out there are just made for decoration, they can hold a huge prejudice & conspiracy vs 1 member, who will judge them anyway? but ofc Blizzard won’t have these stupid minds, so players will be much safer from the tyranny/bm of private Discord groups.
Practical tutorials are everywhere, practice maps are also there, practice tools… I only know1.
