seperating tags with commas not spaces (acts_as_taggable)

When ever I read in my tag form, the field is automatically stripped of commas and each space seperated word is a tag. I want to be able to tag with multiple words. Is this possible with acts_as_taggable?

Not unless you refactor acts_as_taggable a bit. The space delimiter is a common property of folksnnames-based tagging.
