Standard Rules

Gravity includes the following standard (built in) rules you can use or modify. These are found in the Rules list (Tools - Rules).
The Watch Thread rule and Ignore Thread rule appear automatically when you first add threads to the Watch or Ignore list. You may not see them at first - Gravity hides them until used once.
Important Words Rule
Use this rule to mark articles as Important if they contain certain words or phrases (to work automatically, it should be Enabled in the main Rules dialog.  

1.   From the Tools menu, select Important Words.

2.   Type the new word or phrase in the New Word field, then click the Add Word button or press the Enter key.

3.   To remove a word from the list, select the word, then click the Delete Word button. You can also right-click a word while you are reading an article, then select the Add Important Word command from the Article pop-up menu to add the word or phrase to the list of Important Words.
  Watch Thread  (W) Rule
Use the Watch Thread rule to follow a particular discussion thread.  

1.   In the thread pane, right-click the thread you want to watch, then select the Watch Thread command. It is easier to remember and use the keyboard command (W), or use the toolbar icon.

2.   You see the Watch icon in the status column of articles belonging to threads you want to watch. To view and change the list of watched threads, choose the Watch List command from the View - Other Windows menu.  You see the Watch List dialog box, where you can set options for watching threads.

By default, The Watch Thread Rule downloads article bodies.            (Also see the Ignore and Watch Threads topic)
  Ignore Thread  (I)   Rule
Use the Ignore Thread rule to discard a particular discussion thread.

1.   In the thread pane, right-click the thread you want to watch, then select the Ignore Thread command.  It is easier to remember and use the keyboard command (I), or use the toolbar icon.

2.   You see the  Stop icon in the status column of articles belonging to threads you want to ignore. To view and change the list of threads being ignored, choose the Ignore List command from the View menu.  You see the Ignore List dialog box, where you can set options for ignoring threads.            (Also see the Ignore and Watch Threads topic)
“User-Specified Word in Subject” Rule
Use the User-Specified Word in Subject rule to find articles that contain a word in their subject lines. The rule marks found articles as Important. But you could edit it to add to the score and so forth.
When you first install Gravity, this rule is disabled (i.e., it does not automatically apply to incoming articles).
When you run the rule manually (through the rule dialog bar or through the manual rule dialog box), enter the word you want to look for, then Gravity searches for the word in the subjects of articles in the current newsgroup.
Enable the rule to search for a user-specified word in article subjects and mark found articles as Important. The rule will open a dialog and ask for input every time you fetch article headers.
Tips
Most users accept the default actions for these rules, but advanced users can edit them. For example you may want to add to or subject from the article score. Or to not download article bodies for the Watch Thread Rule (they will still be flagged and watched).
If you accidentally remove one of these rules or have upgraded from a previous version of the program and do not see them, you can re-generate these rules by deleting all your rules then re-starting Gravity.  If you want to save your current rules, you can export them before deleting them, restart Gravity to re-generate the standard rules, then restore your previous rules by importing them from the exported file.
