"Generated by XStandard" tag at the top of all posts

Nice editor, but do we have to purchase XStandard Pro to get rid of the tag that reads

-- Generated by XStandard version 2.0.0.0 on 2008-02-21T08:19:16 --

at the top of all body text fields?

If not, perhaps this should be mentioned in the module description (perhaps right after the text that says that it's not open source).

Thanks
