You're nearly there. Instead of storing a comma-seperated list of IDs, use
a third table, say "chores" or something that fits in with your data. Give
that table 3 columns - an ID, a user ID, and a todo ID. To link a user with
a task, insert their ID and the task's ID into that table. To get the
user's tasks, simply join the chores table with the todo table, and search
for a particular user ID. That's a much more efficient way of storing such
relationships.

Is that cool?
