Am i right in thinking that there is no manuals for any

Am i right in thinking that there is no manuals for any of the plugins, like zero information on how to use them whatsoever ?
Maybe i am being blind here but in manual link at the top there are no links to manuals for any of the plugins and honestly the plugin that i have tried so far has been a let down to say the least, it does not work like it works at the WPMUDEV site itself or Edublogs and the support is non existent right now 24/7 it is not.

Not very impressed at al right now.
