I recognise a few SLU posters over here (including myself -- I actually came from SLU to here), using the same forum name. I didn't *lower* myself to come over here -- I actually used to be active on the official forums years ago. As active as I ever am on forums, anyway, which isn't much. Then I left for SC and SLU when this place became somewhat toxic, although I'd be hard-pressed to remember the specifics.
I came back here recently after finding an answer to a mesh question. I then read the current threads and it seemed a lot less hostile than what I remembered.
I've been on SC, then on both SC and SLU, and I've never had any issue on either. Never felt attacked or trolled. On the contrary, I've made long-lasting friendships both in SL and in RL -- the same type of friendships that can be made over here, with the forum cartel, the daily threads, etc. Granted, I'm not confrontational, but some others on SLU are, and they disagree for pages and pages (so much for a hive mind, LOL). Same as here. You see threads where people disagree -- there's a couple of active ones at the moment -- and that's fine.
As for the stats and awards, frankly, I don't give a flying toss if they're lost, and I'm pretty sure the vast majority of others won't either. The awards are super-silly and meant to be that way -- just a bit of fun. We just want not to lose a community that's years old now. I suspect people who've posted here for years would miss this place just as much if the official forums were closed, and would jump at the chance of keeping the community together on another forum.
So, basically, my experience of SLU is very different than yours. I know forums tend to diss each other -- SC used to diss the official forums and SLU, SLU dissed both others, and the official forums did the same for SC and SLU, and I find this very silly, because all three forums are actually quite good.
