Bought it… now what?

So a couple of weeks ago I went ahead and purchased my .com – so now what?  I guess I was all excited to buy it – then after words it struck me, duh!, it costs monthly to host … nice planning.   Although it doesn’t cost much, I guess I didn’t think it through.  Not a problem though, I know that some plans host multiple sites – and where my bil’s site is hosting from, I can add mine on.  Only problem right now is that he doesn’t have the do whatever option on – he’s only paying for basic right now.  I’ll have to hurry up and get his “custom” website up and ready to go so he can change his otpion to allow coding for customizing and not just using their pre-made templates.
