comment Multiple Layers in Geoserver
Would you mind sharing your SLD-file somewhere? Maybe there is some other error in there. Also, these two links might help you along (if you don't already know them): Polygon styling and text styling.

comment Multiple Layers in Geoserver
So you are stacking three vector layers above a raster map of Europe? Fonts and colors shouldn't change because of this, do you really use the same SLD-styling for all vector layers?

comment How to avoid random transparent pixels in georeferenced grayscale raster images?
You mean manually in GIMP or Photoshop? I though about that, but it deemed to be a rather inelegant solution. Also, I have GeoTIFFs, but creating some world files wouldn't be too hard, I guess (just to keep my georeferencing).

comment Display Point Labels in QGIS
You might also want to use round(decimal,places) for prettier labels, e.g. round(X,2)||' - '||round(Y,2)

comment Sourcing GIS data from First World War (WW1)?
Oh, I just realized that I totally missed the letter "m" in "1:10m scale" up in the question... just ignore the second half of my first comment, please!

comment Sourcing GIS data from First World War (WW1)?
I just spent an interesting afternoon in the current WW1 exhibition in the German National History Museum in Berlin a few weeks ago. They had lots of historical maps, but they were all at least 1:1000, mostly 1:10.000 and up.

comment Sourcing GIS data from First World War (WW1)?
Not that I knew about any such repositories, but what kind of data are you looking for? Frontlines? Old cadastral maps? Battle plans? and 1:10 is a really, realy big scale. Even a floor plan for common shed is at least 1:200...

comment Auto populate field as concatenation of other fields
Exactly. I love to open a dbf file, temp save it as .ods file, and then work away with self-updating IF/THEN formulas, concat-operations etc. When your done, just make sure everything is correctly sorted, and save as dbf again. The formulas will be lost, of course, and only the values will remain - voila!

comment Auto populate field as concatenation of other fields
Actually, I meant "use the field calculator to update your FID column before switching to Calc". I am a big fan of Calc, to be honest - I did some demographic work a while ago, and changing age groups or counting certain populations is just so much easier in Calc, because there is less of an interface in the way (especially if you're quickly testing various alternatives). This might change with the new field calculator bar in 2.4, tough.

comment Auto populate field as concatenation of other fields
As long as you have a correct FID field (use the field calculator in QGIS before switching to Calc) you can resort your dbf in Calc as often as you like. Just remember to restore the correct order before saving - otherwise your attribute data will be mixed up.

comment View tiled shapefiles in QGIS 2.0 or greater as one layer?
You do seem to be right about MapServer - the documentation states that having a vector tile index might boost performance: mapserver.org/de/optimization/tileindex.html

comment View tiled shapefiles in QGIS 2.0 or greater as one layer?
I have to admit, i only have ever heard about tile indices for raster files. Why do you need such a index file for your shapefiles at all? I doubt there would be any performance advantage in QGIS even if such a plugin existed.

comment Invalid geometry
Clicking on the error message in QGIS' topology checker will bring you to the potentially problematic vertex or line. Do any problems show up when you check manually(most probably zero-length lines or overlapping geometry)? I can also imagine that ArcGIs and QGIS topology use different tolerance values (in this case, QGIS would have narrower ones...)
