Any professional tips for a newbie IT admin?

[sai1]

Hi,

I just got my very first job as IT coordinator this week and I'm quite nervous about it as much as I am happy to get the position.

Does anyone have useful, sensible and professional tips for me?

Also, can anyone please suggest me good IT forums that I can be part of and ask, answer and exchange topics regarding to IT stuff at work?

Cheers.
