the forum is meant to be post/response/counter-response 'thread' and changing your name would make all those posts in reply to you will look rambling about someone who does not even exist on the forum!
so, technically it is possible; but not feasible.
similarly, i received a request to delete their username and delete i did; but the name will not go away; it is just that the user will be unable to login and post.
from an individual's point of view, "just me" it may look unfair, but from the perspective of the forum, the community, it should be that way.
PLEASE DO NOT REGISTER AND POST IF YOU WISH YOUR POSTS TO BE DELETED IN THE FUTURE.
How do I create a post, or whatever it is called, the one where you can get other people to see it also?
Click on the Forums tab.
You will see a list of contents. These are known as 'categories' which are fairly self explanatory. But if you need a little more description hover your mouse over the category.
Decide on which section to post in - if you are new and you don't know where to post, don't worry; moderators will move your thread; after making a few posts or reading on the forum, you will know where to post, in sha'Allah. Select that category.
Click on the top-right corner you will see a small bluish button "Post New Thread".
Enter a meaningful title and type a meaningful message:
If you have any attachments, click on "Upload a File" and follow the instructions.
Click the button Create Thread:
Your post will appear instantly; however, moderators may move it or delete it according to the state of the post. Please be sure to read our 10-year old forum rules.
ps: i did not make this up; someone asked this question in those very words, except that i edited punctuation.
