Comments disappear from Grades after being posted from FAWeb. They were originally copied and pasted in Rich Text Format from Microsoft Word, and the first few lines appeared as gibberish. When viewing comments in Grades afterwards, the first lines of gibberish are no longer there.
Paste comments into a plain text application, such as NotePad, and recopy them from there prior to pasting into FAWeb. This will remove the Rich Text Formatting which can cause problems when posting to Registrar's Office and running report cards or transcripts.
