Please upgrade to 2.3 here.
The 2.2 and earlier branches are no longer being updated.
I've released a new version with some minor, but useful changes:
Version 2.1 - 20.12.2006, Jazzman
- Removed version check as it isn't really necessary
- Added new SaveAsDialog function which allows filenames with spaces
- Fixed a security issue, where discussion attachments could be downloaded by any user (even if you weren't able to view the discussion itself) by just altering the URL and attachment number (Thanks to jaz!)
Download: Attachments 2.1
Upgrade notes: just copy the files over your existing installation.
