I would like to build the message board on my personal website.

Anyone who visit my website can leave messages freely on this message board.

Can I name this message board free board?

The Free board makes sense??
'Free board' sounds more like meals are included. How about 'Open Message Board'?
Students: Are you brave enough to let our tutors analyse your pronunciation?
Thank you for your answer.

How about Free Bulletin Board ?

Is it the same as Open Message Board?
Yes, that would be fine, too.
