I'm going to be harsh. I'm going to put on my simon face (from idol) and give you my harsh opinion.
Some of these things... Need to go. Really, really need to go. If it doesn't really strike me as important, or is too old, just prune it!
I recommend removing the sticky on the following topics:
-Glest Blender Video (reason, can be inserted into modding overview)
-Glest Models Available for Download (reason, old, nobody uses 3dsmax, and easily found via google)
-Outlines available for all (reason, post-dated, replaced by glest guide, which has topic in general discussion)
-Free textures/sounds/models/knowledge (reason, can be merged with modding overview)
-Game Art Tutorials (reason, can be merged with modding overview)
-Glade Team Project Dark Magic (reason, unfinished mod, popular enough topic that it doesn't need to be stickied)
