If you want to make the text in your signature uppercase (in capital letters), please never change it directly in a user profile. Some servers could mark it as a spam.
You need to edit the signature HTML Source code a little bit.
Go to section Signatures
Select the template you want to edit
Click on the Source button
Now find the part of code (text) you want to make uppercase
Add this piece of code as a CSS style of the element:
style="text-transform:uppercase;"
6. For example the code is:
<div>{firstName} {lastName}</div>So you need to add this inside the first div element. The final code will be:
<div style="text-transform:uppercase;">{firstName} {lastName}</div>If you're not sure about the process, please contact us via chat or write us an email.
