Not by choice they didn't. The old sx channel no longer works for anyone except a very small group of individuals (which I will leave unamed). Because of this people were forced to eather move to nx's channel, or vgr. Most went to vgr.
The new channel will have different admin then the previous sx channel, most of who will be sx'rs from long ago (before I even came here). We still don't have bots for the channel, but should have some within the next couple of days, hopefully...(an hour after the channel was first opened someone came in asking for romz/isoz).
