Can Members Post into Collections?

Hi,

I'm building a site using Perch Runway which will contain a lot of user generated content (news, jobs, events). I would love all the content to be searchable, and easily managed by the site's administrators.

So I was wondering, would it be possible for signed-in members to submit information directly into a Collection? I guess I could created the collections, each with their specific temaplates, and then try and reverse-engineer the database structure and write my own SQL query to input the data into the database - but this feels a bit messy.

Is this functionality possible?

Thanks!
