A question about directional arrows came up on the udig developers list:
"How to style line features with an arrowhead at either end? Preferably using SLD, other methods are welcome if SLD does not support that. I found this thread on the subject: http://www.nabble.com/Directional-Symbology-td12231197.html ...but it does fully answer the question. Given a line feature type with a LineSymbolizer, if I define an additional PointSymbolizer for that type, where do the point symbols get placed? At the first vertex, the last, somewhere in the middle of the line? Do I have to create an additional point feature just to position the arrow icon on a line feature?"
So I pointed him to a geoserver blog post on that very topic and the poster was able to implement a solution quickly.
Communities are awesome.  How's that for tech support?
