Yeah I did the same a couple years back and just returned to the HIVE this week.
Going to be a grind to get back to Dolphin from Plankton lol since I don't plan on pumping cash into the account but I do enjoy blogging my photography and interacting with the other photographers around the HIVE.
Haven't even looked at what is left in the splinterlands account as I did a complete liqudation on it with only a few low lvl cards remaining I couldn't sell.
