Also since this came up on the cleric list lately too:

Heres just a few things I (lvl 20 and retired to Erud's Crossing)
learned from this list.

How to weave. Essential for a bard.
The cool all instrument attack (starting at 18).
What jewelry to buy for myself (Jagged bands, Oppaline Earrings)
About those +15 CHA beer mugs that people let rot in Ferrot.
An unbelievable amount of game mechanics (92.34189% from John Kim)
How to charm/solo with the bard song. (Though I never did this, but I
told my friend about it, since he couldn't ever to get it to work)
