(I chasnged the title of the thread as, of course, the brackets were stripped out)

We filtered them out because they actually cause some serious damage to the display. This looks like it is an inconvenience to you and I apologise for that. I rather think that we have to stick with this but you can alter your own system with a one line code edit if you wish:

File sf-control.php around line 119:

add_filter('sf_show_topic_title', 'sf_filter_square_brackets');

you can comment out that line (easest way is to put a hash synbol in front of it (#)

However, if you encounter a 'topic view (posts)' that displays as what I can only describe as a complete mess, this will be the reason. I will look into an alternative method rather that the hammer technique!

Sorry for the dumb question 

# add_filter('sf_save_topic_title', 'sf_filter_square_brackets');

Ahha

This wasn't a big problem for me so I only have to thank you for your promt answer and
wish good luck with further devolpment of the project!
