Thank you @sama55 for your response. That works now.
Also, can I set HTML message for all logged in users. I also want same text box/option given in above screen shot from "user section for admin".
Please note I seen given some HTML boxes/options from "layout section for admin", these options are not working as per my expectation because some of running top or between question body question title.
I just want same progg code as given in SS with "all logged in users" in place "new registered users". Can I do it? Can I copy & paste that code?
Could you please tell me if there is any possibility with that code and file name to edit.
Thanks in advance.
