No way to know how long, CD. Flavio has had server problems before, so this isn't a new thing. The other times, the forum has only been down a day or two or three. It's definately been longer than that this time.
Regulars? I don't usually hang here, so can't say how many folks came from here. This seems like a nice place, tho'. I've added it to my links.
It's a pretty good forum. Lots of knowledgeable folks just like here. I use both sources. Flavio keeps an eye on that one so feature requests are often developed because of it.
