Fixed Taxonomy

I am wondering if there is a way to established a fixed tagging system? Basically I want to standardize my tagging system so that users are unable to misspell names, words, phrases. If for example, one user tags a photograph with "Alan Moore" and the next plans to tag a different photo with "Alen Moore", is there a way for the system to detect if the user is beginning to spell A...l... and to then give the user a drop down of the previous tags that start with A...l... ?

Hope that makes sense. Thanks!

The next version of Omeka will include a tag "auto suggest" feature, that will shoot down a menu of previous tags, to easily avoid misspelling them. Is that what you're looking for?

Yes, this is exactly what I am looking for. Thanks!

Related to this, can you pre load a list of tags that the auto suggest would draw from? The pre loaded list of tags would not be associated yet to artifacts. Does Omeka support this? How?
