Just a few instructions, in regular indexing there are different directions with different documents, like index what you see, not what you know it stands for.....etc
We let the computer index Geo as George. Or Wm as William. The computer expands names under it's programing and we are to let it.
The Review Names volunteer activity is different than indexing. You are just reviewing highlighted names and indicating if they are a match (correct). If they are incorrect, you can edit them. Please note that Get Involved includes multiple different volunteer activities.
