I'm planning to develop an ecommerce site using Actinic (probably the Express version to start) and hosting it on PlusNet.  Does anyone already do this and have any comments/rants/suggestions?

My understanding of Actnic Express is that they host it and you point your website to it. From their FAQ

Actinic Express automatically provides you with a unique shop address to access your store directly. This will be in the form of:

    http://shop1.actinicexpre...co.uk/shops/myonlinestore
    (where myonlinestore is the name you give to your store)
Simply add a new link on your existing website with your shop address and customers will be able to click directly through to your store.

I dont believe you can actually host the Express version on your Plusnet webspace if I'm reading that info correctly.

Thanks, Mark -- you're quite right, and I've started to build my shop already.  I have a domain registered with PlusNet which I want to use for my shop, and Actinic have given me the IPv4 address to point it to.  I've added a DNS type A record for this domain using the page in my member area here, but when I try it I'm still being sent to my PlusNet website.  Is it just a matter of being patient or do I have to do anything else?

I've just tried 2 of your domains (the two which are similar) and I hit the Actinic default page with both albeit with a notice stating

So it would seem that you've pointed it correctly but still have to configure the shop.

Are you perhaps seeing a cached page when trying to hit that domain?

It was a matter of patience and a steep learning curve on DNS record management!  It's coming together now - thanks for your help.
