Nigel,
I think what is trying to be said is that if you want to put posts up to sell stuff, then no problem, just say that.
In fact, you would be well advised to contact the site administrator and place a banner advert on the site. This way you won't have to repeat your posts, and everyone who visits the site would see information regarding the useful products you offer.
And by the way, I do websites, and here are some things to consider.
You will need to ensure it all works, making sure all links operate satisfactorily. You will need a computer man to write the code, but any computer minded person can do the rest.
Any other website issues, I will gladly help with (at a fee)
Hope your business goes well.
Cheers,
Craig.
