Currently the message you get when User:Foo writes on User_talk:Foo is:

| Foo mentioned you on the Foo talk page in "Bar".

This should definitely mention that it's a user talk page (and similarly for other namespaces), e.g.:

| Foo mentioned you on the Foo user talk page in "Bar".

It should also special-case for when a user is writing on their own talk page, which is quite common:

| Foo mentioned you on their user talk page in "Bar".
| Foo mentioned you on his user talk page in "Bar".
| Foo mentioned you on her user talk page in "Bar".
