I’m just showing code snips of a problem and keep getting the error “Sorry, you can only mention 10 users in a post.” when I try to post.

What am I doing wrong?

Thanks,  
Brian.

Hi @bkoenigs ,

Not exactly sure what’s causing the issue, but I reckon there might be lots of @ characters in there? This character is used to “mention” a user in a post (so they can get notified and whatnot), like @bkoenigs or @Thijs , etc… Somehow it seems your text must’ve contained more than 10 unique @somethings in it…?

In principle, these should be ignored when you put your code snips between code tags, or triple ticks like I’ve explained [here](https://community.mrtrix.org/t/formatting-tricks-for-increased-readability/34/2). So maybe try making sure your snippets are indeed put between a pair of triple ticks (both on a separate line to be safe). As you’re doing that editing, you should see in the preview on the right of the editing field whether the markup gets interpreted correctly.

So, use…

````auto
```
snippet
```
````

…or…

```auto
[code]
snippet
[/code]
```

…to obtain…

```auto
snippet

```

…in your post.

Hi Thigs,

That’s it. There are some characters in the log file that are shown by less with a bunch of '@'s.  
I will post as suggested.

Thanks,  
Brian.
