Question about HTML pages

Hello, I have a forumotion forum (obviously) and I have a big project for which I am planning to add about 700 HTML pages to my forum. I already started to make these pages, and then I realized I don't know if I can host that many HTML pages with the basic, free version of my forum, or if there's a limit or something. I don't really want to pay to have my site hosted, and I don't want to host it myself either, so I'm really hoping I can host it on forumotion without any problems, but yeah, I thought I'd ask before doing all this coding, so I don't do it for nothing.
So, can I add 700 HTML pages to my site, or would I absolutely have to upgrade it in some way?

Ok I'll find a way to do this with 500 pages
Thanks!
