adding link to "/event" page

I want to allow anonymous users to submit events to the calendar (the "/event" page, month view...). I've already made a webform to do this. I want to link to the webform from the calendar page (this seems like the most likely place a user would look for such a link). But I can't figure out where to hack... I tried editing the event.theme and event.module files, but couldn't find how to add content above the calendar table itself (only how to edit how events appear within the calendar).

Is this hack possible?

I also tried to use Views to create a custom month-view calendar, but it seems far too complicated to use a Table View and allow users to browse between multiple months.

Any ideas on a solution would be appreciated!
