How to delete previous topics?
Admins can delete them.
How can I get in touch with admin? Can we?
I am an admin. What do you need to delete?
Could you please delete all of my previous topics, please?
And also how to avoid receiving others’ question from the forum?
That defeats the purpose of the forums, we keep questions up with answers because it allows others to read those questions and to learn from them. Why would you like them deleted?
