I think the big frustration with questions like this isn’t that people don’t want to help it’s that the OP often times hasn’t tried to help themselves.
Tech savvy or not, you’re capable of using Facebook. If you can use Facebook, you can use YouTube.
If you can use YouTube, you could have easily typed the words “how to use the Thailand evisa system” and found one of dozens of videos like this, without being berated by the comment trolls in this group.
