Please clarify your question, because I don’t know what it is “Fellows”?
he means to say other members
You cannot mention other members in your question and I think it is not necessary to mention we are posting questions related to gambling and casinos here.
Just type @ and then username of that member which you want to mention.
for example: @hafiz786? what you want to ask?
@smith is correct for mentioning the method to tag members. just type @ and then the username of the member.
This is not allowed us to mention any specific member and only gambling information you can post just.
