I totally agree with Caroline on this point. The options of the plugins and rules are sometimes overlapping and not very consistent.
For instance, if you activate the option "send old articles" in the AutotweetContent plugin, this will completely ignore other rules. Category restrictions of a rule are ignored, I therefore have to specify a posting filter in the plugin.
This is really confusing. You should think of integrating most options in the component, not the plugins.
