We have just created a Yammer Account and the link to our account is link this https://www.yammer.com/mydomain.org.uk/
I want to hide the word Yammer.com
and mask it with the word social
so the domain will look life this.
social.mydomain.org.uk
So If someone will open social.mydomain.org.uk it will show https://www.yammer.com/mydomain.org.uk/ but the address will be masked by social.mydomain.org.uk
I'm not very technical but I know how to change DNS and can upload htaccess file if someone can kindly tell me what exactly am I suppose to write in the file.
