Hi Bitcoin talkers I am glad to join this forum
I will now proceed to reading the forum rules and regulations so I can benefit and also be of benefit to this forum
I also noticed that if the page is refreshed during registration the image captcha doesn't change
Is this a security problem or it is normal on this forum,?
