do this correctly. It should go without saying to *BACKUP YOUR DATABASE*
before attempting anything here.
This module will not automatically migrate user signatures, because this
process may take a long time. After installing the HTML Purifier module and
then configuring 'migrate.php', navigate to Settings and click 'Migrate
Signatures' to migrate all user signatures.
The version of HTML Purifier bundled with is a custom modified 2.0.1.
Do not attempt to replace it with a version equal to or less than
downloaded from the HTML Purifier website: the module will combust
