Can I install sitemap generator beta on domain without vBSEO license?

Hello,

I'm a customer of vBSEO and I'm very impressed by its capabilities. I've recently started another forum that's gaining traction. I wish to buy vBSEO license once its Gold Final. I wish to know whether I can install sitemap generator beta on this new forum now?

Yes, If you are using vb standard urls on vb4.
The first option in the sitemap options panel asks if you have vbseo installed or not. Just make sure its set correctly and it will generate vb urls in the showthread.php?t=123 format.
the generator will NOT generate correct links if you use any of vb's built in seo functions.
