I am Stepintime, a user from the Alternative History Wiki, a creative writing wiki where people can write whatever stories they wish concerning alternative history.
I agree that Harry Turtledove is a great author for the Alternative History genre, and I think there may be an overlap of interest between the Harry Turtledove Wiki and the Alternative History Wiki.
While I visiting I saw that your Wiki had a list of other alternative history wikis, I think adding the Alternative History Wiki to the list would be good for users looking for Alternative History Content.
If I was given permission I would also like to write a couple sentences about the Alternative History Wiki, on your Alternative History Page.
Please come visit our Wiki, and feel welcome to contribute! Have a nice day
