Hello,
My old account has been hacked in 2011, most likely due to database leaks. Some of the posts contain personal information that I would like to remove.
I'm not sure what was the original e-mail for registration, but I can give a guess.
I can provide details of ISP and the city I signed...
From what I've understood you want to upload an image which is clickable and takes you to wherever it's linked?
Upload the image to whatever image hosting site (imgur)
Go to your signature, click on the "Image" button and insert your image.
Select your image (highlight it using your mouse)...
