I currently host around 40 Home-Starts with a couple more in the pipeline. I also started working with Matt Hann and Tanya Freedman (HSUK) and look after another 40 sites there on a three month rolling contract. The additional 40 sites are based on one promoted by Rutland Online who are no longer developing sites for HSUK. These sites are also in the same hosting you are in, just in a different account. My role is to maintain them each month.
I have hit quite a few problems in the way these new sites were set up. To help people there is a page you can also use here https://wingrove-media.uk/hsuk/ which lists those websites, but of greater importance, at the bottom of that page are some self help guides. You are free to use these if you wish. Some relate to the way that the hosting works, some relate to specific issues in that design of website. Many are relevant to you as well.
#BehindTheMask
I have just added one which contains a specially built slider to add the existing slides used on the Home-Start home pages to help promote #BehindTheMask. Please do help yourselves and download your copy of the pre-built slider and the instructions. It only takes 5 minutes and I have done the hard work for you. Note that the dimensions of the sliders used on your sites are different to the ones used on the HSUK sites. I have done two sets, just take care to pick up the right one.
I also have a couple of posts prepared which you could also import and publish including the graphics. Contact me for more information.
