Events plugin - How do i add arguments for example rather than just the last month by default?

I do have a couple of questions after trying to set up the plugin.

1 - Newsletter plugin - Is there any way to upload a list of email addresses and send the newsletter to that specific list rather than a specific user sub list?

2 - Events plugin - How do i add arguments for example rather than just the last month by default? I can't quite figure out how to add the arguments for [eab_calendar] & [eab_archive] for example.

Thanks
