I am successfully able to reset password using link freepbx.org/user/password/ for username gurvinder.dadyala
First of all if dot is not allowed then it should allow you to change password using this username. I am also not sure why it allowed me to register in first place. When I try to login to Freepbx community using same, i get message that account is not authorized. Is it possible for someone to delete my account completely so that I can go through registration process.
Even after password reset it takes to Atlassin crowd profile page and where there is not option to even change username.
I look forward to your response.
