Since Project Central has expired, I thought I might make a comprehensive topic on putting up your script for review in the Script Reviews and Collaboration section of the Celtx Forums.
For those seeking Review to their work:
One topic per project allowed. Multiple topics pertaining to the same script or very similar versions of the same script clutter up the forum and can be regarded as trolling.
Please title your topic in a manner similar to the following:
Please Review Screenplay: The Wizard of Oz (Childrens Drama)
or
Please Review Radioplay: War of the Worlds (Thriller)
Begin your post with a short pitch about what your screenplay/stageplay/etc. is about. This is so that people interested in the pitch will be compelled to read the script. You can also add a comment about where you think the script is and where it's going. (Eg. I've written 20 pages, but I'm not really sure about the character arc of Toto, what do you think?) Also, in the case of screenplays, because of the different rules applied to spec and shooting scripts, please state whether your script is a speculative (as in you want to sell it) or a shooting (as in you're making it for yourself) script.
Then, below the submit button of your post, there is a tab called "Upload Attachment". Click on it and choose the PDF file which you would like to attach to the topic. Then click on the "Add the file" button.
You are now ready to submit your topic and put your work for review.
Remember that those who do critique your script do it for free and without any obligation. It is, however, polite and of good etiquette to review one of their scripts back for a review you have received.
For Reviewers:
No three word reviews allowed. If you're going to write a review, write an informative one.
Critique must be constructively presented and you should be able to point out what you think is wrong and what you think is right about the script you are reading. To be insulting is to be ignorant, but one must be honest in their critique so that the review is not in vain.
Do not expect a review back, but analyse each script as best you are able and you may get critique back on your own work.

Suggestions on additions to this are welcomed and greatly appreciated.
