The Wiki has moved again.
http://hetalia.wikinet.org/wiki/Main_Page
This Wiki seems to be undergoing the proposed repurposing. Thusly, the in-depth character pages have been removed and now redirect to the full character list with shorter descriptions.
If you wish to contribute to the full wiki, you must re-register on Wikinet. I advise editing on Wikinet so as not to conflict with the repurposing.

See the following links for details.

Should we move again, I advise lurking Hetayume from time to time to see updates about the Wikis.
