Should I install the forum in root? as in www.mywebsite.com
or Should I install it as a sub-domain? like forums.mywebsite.com
Or is it better to install it under a sub-folder? like www.mywebsite.com/forums/
Note: If I'm not going with having the forums as the root folder; I'm planning to add a WordPress blog in the root and installation the forum as a subdomain/subforum. Is this not recommended?
