I am confused about many things
 

I opened a free forum using zetaboards three months ago. Since then my forum has increased in activity and has grown very popular. One of my rivals(our sites have the same genre) previously used zetaboards but when I went to there site I noticed it looked much more professional. They had all types of new and cool features and when I strolled to the buttom it said they were using vbulliten. Well I like what this company has to offer and I read through the FAQ but their was a lot of things I did not understand.

I see that there are many different versions so is one version better than the other ? Is one version cheaper than the other ?


Also I only know basic HTML so will I have to do all of the coding myself ? Or is it similar to zetaboards where you just register the forum and they basically have everything set up for you and you just make minor changes ?

What is there to download ? I use many different computers so will I have to download the software on all of the computers ? Will I have to pay to download the software on all of the computers ?

Furthermore, I went to another site that said they host vbullitens for 5:00$.

What does it mean to host ? Also I am a teenager so can I use my parents credit card for this ?
