Anonimous users can edit pages, comment on articles and blogs, and put messages on message walls, on UCP wikis. Unless the local admins chose to prevent them from.

Anonimous users cannot comment on "Discussions" and don't have their own message walls, at least not at this point. There are also some bugs in regard to anonimous users.

About you not being able to edit - can you provide more details? Which wikis have you tried to edit on, and what type of edit exactly.
