Tradeskill Level Caps

[Ikonoclastia]

Are there level caps? I'm trying to increase my Fletching so I can make magical arrows but I'm wondering if its not increasing because its just slow or because its capped at my level, its 68 and I'm level 13.

I realize that fletching is not economically wise but I'm a ranger so I must fletch.

Edit:

Oh yeah I did a search for about an hour, found this site http://home.comcast.net/~aoenla/fletchguide/index.html

But more of the other stuff I found wasn't classic specific... hard wading through all the 2010+ posts
