Of course you will be able to work on more than one skill, you will be able to increase your skills as you gain experience... What was discussed in that thread was mainly if one should gain experience that could be used to increase magic skills when you got the experience from slashing down a mob with an axe..
Kinda like the way you gain experience in \"The Elder Scrolls\" 2 and 3, or \"Allods\" 1,2,3...
