In my Dungeons & Dragons group(s), we have a player who can never remember ability scores, spells, bonuses, etc. We currently have two groups, and he is in both. We enjoy playing with him, but it takes forever to find his stats. In our main campaign (7 sessions in), his character sheet is crumpled, only half-filled, etc. So my question is as follows:
How can I get a player to remember his character's bonuses or at least make finding them take less time?
