Besides Worldprofit, I'm involved in a couple of other adventures (as I like to call them). I find them all very useful and helpful in building my own business empire.
Another site I use is G.D.I.. It's only $10 for a domain name with website hosting and a website builder. You get your own membership site to create, your own forum to create, your own press release site to create, webmail and plenty more. It's set up for beginners but also has everything else in there if you're more advanced.
You can also promote G.D.I. it if you want to make money. I promote it, and our upline advertises for us as well. It has a deep residual pay-plan.
There are investment options as well since it's growing popularity with .ws domains being international.
OH, I almost forgot, they pay you $25.00 to do the training and they give you 8 weeks to complete it, but you can do it more quickly if you want.
They don't keep trying to get you to upgrade in things or buy extras.. it's just all what it says it is. No fluffy stuff.
What excited me the most is the membership site, but I find everything about it very useful!
Thanks for looking!
