I'll start.

Read the stickies...and we have a Wiki. All the information you asked about and lots and lots of discussions can be found there.

Biggest suggestion I can give right now. MAKE DAMN SURE that you are the OWNER of both accounts. If "a friend" gave you the second...or your mom...your brother...your neighbor's dog...don't box with it.

End of dire warning.

Now don't be lazy and go teach yourself!

Good luck!
