Now a days most of the forums asks for user verification/validation through emails.How will you trust the authenticity of the site, will they spam my inbox, will they sell my email address to third party?
Don't worry... there's something called disposable emails. Get some random email ids which lasts for a small time duration.
On visiting the site you will be given a temporary email id (some junk email) and a mail box which you can for use any purpose... there will be a life time given for that email ids, some sites gives 10 minutes, some 60 minutes etc. You can even extend the life time in some of the sites.
During this life time you can get messages to your inbox, reply to the messages.
