I hope that if the site ever does permanently go down, that we will have notice and time to prepare. Even something like creating a CelticsStrong sub on Reddit could help keep everyone together and give us a chance to reconvene before deciding on that as a solution of finding a more permanent one. I've been in touch with some people on this site for 20 years. It would be weird to just have that vanish one day. It's not like we all have each other's contact information. Maybe most of us would at least try CelticsBlog(?).
Of course I hope to see the site continue on for many years, but there are free and easy options out there. It'd be a bummer to lose the history, format and TPs for sure, though.
