Well, firstly, my apologies for not being able to appear at an event I did set up myself

Sadly, after a moderately pacific last year in terms of my RL job, this year has been a complete and utter nightmare - I can't even predict accurately when I'll be at home before midnight, my time. Ah well, enough complaining

I'm glad to know that there was enough attendance at the Neualtenburger repeater for the Town Hall meeting.
The issue of clouds in high places is something that happens all over the SL world. Most people rarely find such a cloudy region as Neualtenburg, because few regions are above 150 m on an average (I think that's the "cloud level"

. All the city centre is above that value, so, naturally, we get the clouds quite often.
According to LL, there is a "weather system simulation" somewhere. This means that we don't have
always cloudy days, but we get them quite often - most people never "see" the clouds even if they're there, unless they fly up.
What is more annoying is not the clouds
per se, but rather the time they take to load. After all, they're textures like anything else (or textured particles, I'm not sure) and they wait on the queue for being downloaded by our SL client, like any other texture. Thus, before they load, you get those very strange "lighting effects" ("solid" bands of light permeating everything) which annoy people most. Because when the cloud textures fully load, they're pretty transparent, and just give it all a "foggy" appearance without seriously disturbing the view.
Sadly, there is no way to "prioritize" textures to load that I know of - this means that, if the Lindens could achieve a way to get the cloud textures loaded
before anything else, I guess most people wouldn't notice the difference. They would only see a "foggish" behaviour, like you see when flying over 150 m - it almost never disturbs yor flying around, because at that height on other regions, you usually don't have anything else to load (few textures around), specially if your drawing range in Preferences is set to 128 m - so you just load the cloud textures quite fast and never really notice them much.
It's just in texture-intensive Neualtenburg that this effect is quite visible.
Clouds cannot be set with the Estate tool, so the only choice would be to lower the whole of Neualtenburg - which, unfortunately, is very hard to do, due to the current layout of the terrain.
Ah well. Like Aliasi, I like them a lot, and I also think that the clouds add to the mystery and uniqueness of Neualtenburg. You can't have a change in sunlight (I mean, the sun's colour is always the same in the whole of SL), and a medieval city looks too clean and tidy when rebuilt in SL, so, the clouds and its foggyness - when the textures fully load - at least achieve a bit of realism in making details smudgy. I always loved that, although, of course, I also get annoyed at the strange "light effects" before they load properly...
