I tested Custom Comment Text in WP 2.9 and it broke. Here is the updated plugin.
Custom Write Panel is another WordPress plugin in the work. It is a plugin that will allow users to create custom write panels, alongside the existing Write Post and Write Page panels.
This custom write panels will appear under the Write panel, as Write Book Review, Write Aside, or Write [fill in the blank]. When a user chooses to write post under, say, Write Book Review, the write screen will be pre-set with the assigned category (Book Review). It will display certain set of custom fields (Book Title, Author, ISBN, etc).
I have updated Custom Comment Text plugin to resolve the issue of custom fields being deleted after a comment is posted. The issue is reported after the release of WP 2.1
