Our first names only. At first we tried to keep them secret. But when adding stories it got to be too much trouble changing them.
However most other names and places in our stories were all ready changed, or not, to protect the guilty.
Life is so complicated with adult kids.
Yes, everybody on Lit knows my first and middle name... and unless I get doxed, which is totally possible, there are only a few people who know my last name, too.
