The Noble class in the Birthright Campaign Setting gets Leadership at level 3.
A 2nd level Magician can get Skill Mastery for 3 + Int modifier skills.
Unfortunately, this doesn't really qualify for Fun Finds since it's not affiliated with anything remotely close to D&D, WoTC, or even Paizo/Pathfinder.
if one will check my thread of official materials, one will find that wotc blessed specific sites with official status. these sites convert specific campaign settings from 2.x to 3.x that wotc at the time was not going to expend the man-hours to include in 3.x. due to wotc's statement of official status, any material produced by any of these sites is given official status equal to that of wotc published works. in fact, such material is co-owned by wotc and the sites in question. the campaign settings are as follows: birthright, planescape, mystara, ravenloft, dark sun, and dragonlance.
the ravenloft site ended tenure when the license was sold to SSS, and was not picked back up when SSS went down. current status of the license is unknown, but is assumed to be reabsorbed by wotc, as the official site did not return after SSS died.
dragonlance also is no longer considered official as wotc released 3.x dragonlance books followed by other books released under another arrangement which supersede the site.
mystara has stated that they have no intention of releasing official 3.x material, but merely retains a repository of 2.x-->3.x conversion suggestions and guides.
with the conversion of dark sun to 4th ed, activity has dwindled somewhat at the athas.org site, formerly the most active of the three remaining campaign setting sites, but there is still activity and they retain their official 3.x status.
planescape and birthright are still active, and still retain their official 3.x status.
