Disclaimer Wording

The provided disclaimer for user registration is

While the administrators of Curmudgeon's Photo Gallery will attempt to remove or edit any generally objectionable material as quickly as possible, it is impossible to review every post. Therefore you acknowledge that all posts made to this site express the views and opinions of the author and not the administrators or webmaster (except for posts by these people) and hence will not be held liable.

I would respectfully submit that this statement is somewhat grammatically muddled and would be clarified by replacing the words "and hence" by "who therefore".
