I have a rather long chat transcript that I copied out of a window, and when I pasted it into vim, it put two line breaks after every username, and then what the user typing said. I'd like to:

1. Search for the `>` character
2. Go to the top of the file.
3. Start recording the macro
4. Move to the next match.
5. Press the delete key twice to move to move the text up to the same line as the user's name
6. Finish recording the macro.
7. Run the previously recorded macro for every match in the file.

How would one go about this in VIM?
