Hello again...
Could someone help me, please?
I want to delete the attachments in the Paradox Interactive forum Medals / icons thread, because the posts look extremely ugly
(and I will try to find another way to make them visible w/o attachments. I would be grateful if anyone could provide a solution)
Thank you in advance
Agis
