# Editing tags not allowed because not 6 characters?

I was trying to edit the post "Big Bang Anybody?" by adding a tag to it.. While until now, even if I didn't edit the body of the post, I could still edit the tags. However, it seems like from today onwards, to edit the tags, I also need to add 6 characters to the text! At first, I thought of simply adding the followsing text:

$$\mbox{ }$$


However, I realised that then the edit would be rejected (since it is too trivial) and so will the tag edits .

So, why do we need to modify the text body just to edit the tags?

• Strange, I could do it. I mean just attaching the tag and do nothing else. Maybe something has changed only for edits of people who have not yet 2000 rep ? – Dilaton Jun 30 '13 at 8:18
• @Dilaton: I tried a few tests on the post and it is working again. I don't know what had gone wrong... – Abhimanyu Pallavi Sudhir Jun 30 '13 at 9:10
