Hi there,
Unfortunately, we do not have the link setting for the bbcode comment in Easyblog currently. However I've make some quick hack in your site
http://screencast.com/t/yturOHZdI19L
I've make some quick hack in the respective folder:
JOOMLA_FOLDER\components\com_easyblog\themes\wireframe\comments\default.js
JOOMLA_FOLDER\components\com_easyblog\themes\wireframe\comments\bbcode.js
JOOMLA_FOLDER\administrator\components\com_easyblog\themes\default\comments\form.js
I'll extend this issue to our developers maybe we can implement this in our incoming version
Have a nice day ahead
