Plumstead Leisure Centre

I know it still exists as Toddlers World takes place here every Monday and Friday, but whenever I pop down to it I always forget to read the notices or enquire about what else takes place here.
From what I can see on the Greenwich Leisure website, Plumstead Leisure Centre isn't part of the boroughs leisure centres anymore. At least there is no information about it anywhere. Perhaps I am not looking in the right place.
Does anyone know what other activities take place here?
