The old 8th Edition LM Tactica and old army book magic item reviews are both extremely out of date now and should be unstickied. I like seeing my stuff stickied but my own Dwarf and Light Tacticas are not important enough relative to other Tacticas to warrant being stickied. Bob's Cold Blooded leadership thread would be a better candidate for stickies than my old threads. It's debateable whether the Army of the Month is worth keeping stickied The WIP of the new 8e Handbook should probably be stickied.
Your wish is .... I left the Dwarf and Light Stickied because I think they are fairly relevant. I did unsticky all the others that you recommended. Let me know if you have others that you feel warrant a Sticky.
