The Floranext team will point the domain you will be using for your Floranext website when it's ready to go live.
If you would like to forward any other domains you own to your Floranext website, simply log into that domain's registrar to 'forward' those domains to the domain you are using for your Floranext website. If you need any assistance with this, please ask your domain registrar for help.
For example, if the Floranext website was using amysflowers.com, Floranext would point amyflowers.com to Floranext.
Then, if you also owned and wanted amysflowers.org and amyflowers.biz to also point to your Floranext website, you would log into your domain registrar to forward both those domains to amysflowers.com.
This is a common, quick and easy task that is usually free or low-cost. Listed below are links popular Domain Name Registrars and links to their forwarding service:
