My Follows as of today end up in default Portfolio "Portfolio 1".
go to https://seekingalpha.com/account/edit_stocks and select "Portfolio 1".
It seems that a Watchlists feature is missing. Portfolios have a position, performance, etc. Watchlists are for checking back on handpicked groups of stocks. The purpose is to have lists that meet all your investing criteria that you can check and "buy today"?
