History lesson time lol.
The initial V-bulletin migration honestly wasn't what damaged OCN. I mean sure, as with any change there was frustration and some losses. Huddler (the platform OCN moved to) was actually decent and the owners were community focused and were working with myself and the other management to bring back any lost functionality and fix bugs. They were actually exceptionally quick on fixing things and making adjustments. I cannot really find much fault with them. We were making some great progress.
Then came our troubles.
Huddler became EOL as a platform. It was a proprietary software that was no longer going to maintained. Bugger ! Huddler was then purchased and we became part of the Wikia group. This didn't mean a platform change....but we did see stagnation as dev work etc had come to a standstill.
Ironically it was only a short time after that Wikia re-shuffled their company portfolio and decided that tech forums such as ourselves were no longer a good fit....Sigh.
Here comes ANOTHER move.
OCN was the sold to Verticalscope which was running its portfolio on...get this, the same super old version of V-bulletin we initially migrated away from. This meant OCN was migrated back to V-bulletin, but with that meant we lost EVERYTHING. All the features we had managed to get back thus far with Huddler...poof gone.
This is were you would have started to see the mass exodus of users and slow down on OCN. To make matters worse, we couldn't get much work done to restore OCN after the move to Verticalscope as they were already planning to mass move their entire portfolio to a custom fork of Xenforo.
So we stagnated for ages, with nothing unique that made OCN what it was, that was the REAL damage. We eventually migrated to Xenforo which is the OCN of today. The rest you can figure out (I cannot go into details)
