I noticed that some wpforo functions echo directly, instead of returning a string.

For example wpforo_unread, wpforo_phrase, wpforo_topic_title, ecc

This can't allow developers to manipulate the value generated by the functions, nor allow to put save them in a variable.

There are versions of these functions that return string?

(moreover: there is a developer documentation? I didn't find it)

Thanks 🙂
