the main sticking point is the age-old issue of the actual "next/previous site" ring functionality being prone to breaking due to a site being deleted or having its association removed and i'm unsure how i could efficiently handle that
make a new site for the webring, have the next/prev buttons redirect to it with the referrer site's name as a get parameter, have the code you own decide where to redirect. once a month scan your linked list for broken sites and then remove them from the chain if needed.
feel free to follow me whilst i get back up to speed if you're there! 'cause i've simply had it up to here with twitter
You may also need to use "whole word match" which varies based on what you are editing in but it should work virtually in most editors.
oooo thanks for the advice! though tbh i'm more worried about links to my site from other sites being broken, i wouldn't be able to do much about those if i were to change urls
