Hi,
After I selected a user using the "@" feature, I get the issue below.

Hi Fernando,

I think you have conflict with your own css, I should ask this with our CSS designer, but all employees are in holiday in this week, we will give you the solution when they comeback from holiday.

thank you

Hi Fernando,

here the fix:
edit /templates/socialize/css/custom.css and put the following CSS

.textntags-wrapper .textntags-beautifier > div > strong {
  margin-left: -6px !important;
}

Hi Albert,

It worked. Tks!
