How to post
Important: When you want to ask a question, do not send a visitor message, do not ask in the library, and do not post to another existing thread. You need to start a new thread.
Getting Started
To start a new thread, first go to the appropriate forum. You'll find a list of forums on our main page at physicsforums.com. Once you've reached the right forum, click the "New Topic" button as shown below:
If you don't want to start a new thread, but simply want to reply to a post, go to the thread you wish to reply to and click the "Quote" button, circled in the image below:
Do not use the "Report" button to post a reply (that's the crossed-out button in the image above). The Report button sends a message to the mentors (moderators) and is meant only for flagging posts that violate our rules.
A Few Important Notes
- Homework and homework-style questions always belong in the homework forums.
