Im not sure if anyone knows the answer to this.
One thing that i have always had an issue with in buddypress is the fact when you hover over someones name it exposes usernames?
I am currently looking for 2 things.
1: The option to either remove @mention feature or make it use real names.
2: Disable the default nature of when you hover over the name of a member it exposes there username.
The second one is the one i would love work out most even for single wordpress installs to make them more secure.
Any advice would be greatly appreciated, thanks.
