It’s not an exhaustive list, certainly, but I think it’s a good start. Now I just need to figure out who I need to email it to.
*To gain any indulgence you must be a Catholic in a state of grace. You also must have at least the habitual intention of gaining an indulgence by the act performed. To gain a partial indulgence, you must perform with a contrite heart the act to which the indulgence is attached. To gain a plenary indulgence you must perform the act with a contrite heart, plus you must go to confession (one confession may suffice for several plenary indulgences), receive Holy Communion, and pray for the pope’s intentions. (An Our Father and a Hail Mary said for the pope’s intentions are sufficient, although you are free to substitute other prayers of your own choice.) The final condition is that you must be free from all attachment to sin, including venial sin.
If you attempt to receive a plenary indulgence, but are unable to meet the last condition, a partial indulgence is received instead. (source)
