It worked fine for me when I tried.

I'm not sure why it didn't work for you though.

I have experienced this issue as well.

Sometimes it seems to work and sometimes not. I could not find a pattern, it seems very random.

Also, sometimes you can edit and add more tags, and sometimes this doesn't work either.

@Akaisaiah:

1. Do not hijack others threads.

2. This board is not to announce new wikis, even more when there is zero content yet.

3. This is also not how wiki promotions would be made.

4. Read the Discussion Guidelines.

Hello everyone,

Here is the staff reply about this:

I can confirm this is a known issue - only 1 tag can be added to a thread at a time. Sorry for this problem! Hopefully it can be worked on soon.
