Well, well, well, some sad news indeed! Trust me, as Benny26 has noted....."it's not the end of the world"! I know Julio that you and your staff have been busting tail and taking names and doing your very best when it comes to this new place. I don't doubt and I trust you when you say that you guy's have tried to do something about this groups thing and it didn't pan out. I know that when dealing with two different formats of anything, it sometimes can be very hard to get the two different formats to play nice with each other.
Maybe as like Benny26 has already stated, maybe some sort of temporary fix can be implemented, until such time a more permanent fix can be found. Maybe we don't have to worry about trying to import the old groups to this place, maybe XenForo already has a groups feature and we could start fresh and new, I don't mind starting most of my old groups back up from scratch! I think I remember most if not all of what was there and could start it back up fresh and new here.
But in the mean time, I'm sure the TechSpot staff have bigger fish to fry, I'll just practice patience and see what if anything happens in the future!
