Now that I finally have this working.... I have a request after seeing how this works.
1. Ok its great to be able to mark a thread as solved and it automatically adds the prefix [SOLVED].... but...
2. When we change/mark the thread as unsolved that should also automatically create the prefix and add [UNSOLVED] to the thread.
Can you please make that as a new feature since the theme of your day is updating!
ADD COLOR TO PREFIX
For people who aren't so html code trained here is a nice thing to add until the developer builds this in.
1. Add a new prefix to the set and label it [UNSOLVED].
2. Add color and bold html to each prefix in the title (Rich Text) field.
SOLVED:
Code:
<b><font color="#1A5722">[SOLVED]</font></b>
This makes a dark bold green color to match solved issues.
UNSOLVED:
Code:
<b><font color="#C80416">[UNSOLVED]</font></b>
This makes a dark bold red color to match unsolved issues.
3. I also installed a mod which allows me to change the prefix of a thread inline while viewing at the forum level. So I can mass change prefixes.

That mod does not open and close threads though...
