After looking at Karlos' comment I began to think about some of the posters I haven't seen here recently that used to give good useful answers.
There were a lot of interesting (and fun) folk that have either moved on over the years or gone into dormancy. In no particular order, Wilse, T_Bone, FluffyMcDeath, VincentAC, Kees, Glaucus, mips_proc (aka meerschaum), Blobrana, PMC, KennyR, Quixote, uncharted, lorddef, xeron, vortexau, seehund, Turambar, dezignersrepublic and many more besides
