FreeTagging and impossible site maintenance??

Hey all drupal users!

I am launching a new site where people can post some artist content they wrote...

I really want to use the freetagging system so that users can themselves add categories to their content etc...

But here are some questions about this way of handling categories and the supplemental work that it could bring to us...

what happens when people have typos or errors in the syntax of a word, it creates another tag? Generally speaking does the webmaster them as to do some tag cleanup to make sure tags are not duplicating other tags (like peace and paece) for example... I think I can put them in synonyms, but it still means I have to check out the tags and maintain some order on the site...

Seems to me that if I have to maintain de tags on my site, this would rapidly become an impossible task!!

How to you guys manage this, is it simply free for all on your sites?

Thanks
