How do you remove the “Welcome” page and insert the ads?
do you want to remove the welcome page - or change the text on your site homepage? if the latter - then in the admin area - you can manage homepage content very simply.
What do you mean by ads?
- Banner ads (set in managed ads)
- Featured products (set in listmania)
If you want no welcome page text, simply remove any description from the “In this section you can edit the text to be displayed on the store home page.:” section in the Site Layout page in the Admin area.
I also recommend you take a look at my Home Page News mod in my signature below.
