Hey there @Darysson
Thanks for joining S.A Forums
This is a rather old topic by now, so I'm not sure if this user is still active on the forums.
You may want to use the "Message" function from your member account to try reaching him, using the @ sign before a member username in a post ( like I did here with yours ) also insure that the user will be notified, but best is to use the message feature.
Also be aware that teh forums are on public access for reading, no account required, so that's also why it's recommended to use the message function for privacy like contact info exchange...etc.
Hope that helps, cheers !
