We've set up a section on our forums where we'll be posting information about the status of our upcoming UnrealScript 3 IDE.
Note: Regarding forum rule #6: There is no commercial offering for this product. As an offering to the mod community, the IDE is developed as freeware under a strict condition that it be used for non-commercial purposes only.
Non-members can view the forum, but you have to sign up to post in it.
Sorry about the registration procedure (I had nothing to do with it). Here are the steps:
Create an account
Activate the account from the key sent to you in an email
Log in to the portal page
Fill out the remaining information on the Account tab and click Update
After this, the forum link will become active
Before you can post in the editor section, you have to send a request email to UnrealScriptEditor@pixelminegames.com. This is to keep members of the other sections of the site from coming in this subforum acting childish.
