I'm in the same boat. I was an avid user of Wattpad for years, but all the senseless changes over the years (god, don't get me started on how the algorithm was butchered from when I first joined in 2011) kept piling up. Though I wasn't super active on the forums, the forums being taken down was kind of the push I needed to look into other platforms.
I've heard good things about Tapas for the most part, decided to give it a try. Going to give crossposting a try... ^.^'
