Well, I have this blog where I have to activate plugin "Sendit" for both Administrators (which already can use it) AND authors, but I don't know how to or what to modify. There are others plugins that let you assign the minimum user level to access to that plugin, or you can use a custom var min-level, but, how can do this in such a case like this?!
I've tried asigning other user levels and capabilities via Role Manager, but with no luck.
How is a plugin set for only one or several types of users?
Please help me and thanks for in advance.
