Big problem with @mentions

[j.conti]

Hi,

I make a test at ​http://testbp.org

I created a user name : andymentions

I do a mentions of andymentions, that will be at andymentions's and andy's mentions.

May be, are mentions only using the firs 4 characters?

Andy, when you see that mentions at your profile, you can delete the mention and the user andymentions. The user was only for this specific test.

See at:

andymentions @mentions -> ​http://testbp.org/members/andymentions/activity/mentions/

andy @mentions -> ​http://testbp.org/members/andy/activity/mentions/
