Description as submitted by original author Gearshaft:

This addon on adds a level equivalent to the skill bars in the Skills window.

About

This addon is very useful in helping quickly display what level your learned skills, like fishing, are. The level displayed in the skill bar is roughly equivalent to the character level it's related to. It's a pretty simple low overhead addon, but it removes busy work (math) for determining the skill level -> character level conversion.

Usage Tips

Knowing the equivalent character level of of your skills can help out when deciding what to do with them. In the case of the fishing skill, just go to an area that has the indicated level monsters for prime fishing skillup. For weapon skills, the level listed is the level that you are effectively fighting as.

Addon is based on last published version 2.1

Changes from Gearshaft's 2.1 - Skill conversions properly account for the different max skillpoints introduced in BC. Professions max out at 375 points. Basic skills like weapon skill, defense, class skills like lockpicking etc max out at 350 points. - All skill to level conversions attributed properly.
