little BS help to get to 300Follow

ok i got my BS skill to 225 i have done all the mithril order quests in gadgetzan so what do i do not to get my skill to 300


my problem is i don`t know how to raise my skill cap

If you just need to raise your skill cap, talk to your last trainer. He will tell you who you need to talk to next. If you are alliance, the dwarf in Ironforge gives you the name of a gnome in Booty Bay. I've forgotten both names, but all you need to do to get your skill cap raised is go talk to the right gnome. He will train you to artisan. (You also have to be a high enough level - I believe lvl 35 now, down from 40 before the last update). The various blacksmith quests at this level are just to get new recipes or to branch into specializations.
