InfiniteDeveloper To reproduce: After creating the post with some tags, remove the tags afterwards. However, once you do, you cannot add them back. I was able to do it with this post as well...
InfiniteDeveloper Upgraded to Bug Type: MODERATE Reason: You can still remove the tags on a post even though someone has changed them.
flashteens It should be a DISPUTED forum issue. Depending on whether or not ZymSB will plan to fix it, I'll update the status then.
flashteens By current setting, you should no longer to modify tags after someone else replies to your post. So now that I made the comments, the tags should be no longer editable now.
InfiniteDeveloper PARTIALLY RESOLVED. I can no longer remove tags on a discussion where at least 2 or more people sent messages in. However, I can still do that when I am the only one who sent messages in a discussion, like this test one shown below.
