Topic locked and moving to the basket. This slide has given by Shakkhor yesterday. So, its going to basket due to redundancy issue.

Wrong step.

14. Send a topic to basket if and only if:
->it contains illegal materials(i.e. porn, or cracks)
->It is requested by the author of the topic to delete it.

When someone gives something, you are supposed to merge it. Not remove it.

topic moved from basket, merged, and unlocked.

Apparently, some people forgot the meaning of the term "If and only if"

I was the author of that topic, and I wanted to delete it.

And the reason is ?

The same slides are given by Shakkhor and my link wasn't working and I didn't find the importance of uploading the same file again in another server and give the link to download the same slides.

Your link is not working because you didn't buy any space from the host

If you did buy it, then you won't face this problem.

And Shakkhor PROVIDED a mirror link.
(I made it bold, italic, and underlined. Hope it gets past your busyness and gets your attention.)
True, you didn't find the importance of uploading the same file. Neither do I, when someone provides a mirror link.

So you instead of
editing the post, while mentioning that the link is not working, people should use the link provided by shakkhor

decided to move the topic to basket.

Hmm.. cut the head when you have headache. Marvellous!


A moderator is supposed to maintain the continuous flow of topics while you are actually trying to ruin it.

Anyway, the "move topic to basket when author asks" is not standard, and was created because of some whiners at that time.

Apparently, it is encouraging people to whine even more!
