I am currently developing a new blog platform with some new features. For the commenting on blog posts i'll use facebook comment. (each user has to create their own account for comments on facebook).
But i have one problem.
Each user can, whenever they want change their account name (subdomain name), and also the domain they use. ( i have several domains available).
But when facebook comments use the href of each page to sort the comments i am afraid there will be a lot of lost comments for my users. when they change account name..
What happens with the comments when I change the domain / subdomain but keep the folder structure & filename as before? is there a way to convert the old "href" values to the new with the new domain name?
How to solve this? any ideas?
As i understand, the XID value is the old way of sorting comments, and you should use href?
Thanks!
