Ok, so...I should be mining it seems. Only other question would be...where? Im currently using GUIMiner and have joined BTCGuild. Is that aight or should I look elsewhere for GUI's or Pool to join?
That is pretty much up to yourself. I registered to a couple of pools, tried them all out and switched to that one i was most comfortable with.
There is no "best pool" and everybody is only able to tell you his/her prefered pool ..try them, compare them, stick to the ones you "like"
