+## Determining when to award points
+
+To ensure that points are only awarded for the first comment marked as a
+solution:
+
+* Alter the database to allow for tracking of each submission and the first
+    comment marked as the solution. Then, everytime a new solution comment is
+    detected, simply check the database to see if the submission is already
+    counted. This will avoid unnecessary calls to Reddit, which would include
+    scanning all the submission comments each time.
+* This approach could also make it simpler to check whether a solution comment
+    has been edited. Instead of having to do a daily search for edits, it could
+    just check the original solution comment to ensure that it still contains
+    the "!solved" string. If not, it can remove points from that author and
+    award points to the new author.
+
+To ensure that a point is awarded to the correct user:
+
+* We could expand the "!solved" bot summons to include an optional username
+    argument. Without the argument, the bot will award the point to either the
+    top-level comment or the parent comment of the "!solved" comment, whichever
+    is decided upon. However, if the username argument is provided, the bot
+    could simple check that one of the comments in the comment tree belongs to
+    that user, and then award them the point.
+    - Honestly, this is probably overcomplicated and unnecessary, though.
