I’m sorry but we volunteers do not provide email support. Also posting your email address in any public forum like this is not wise. Email address harvesting spam bots will harvest it and you will be spammed, not only that but that email address will be sold to other spammers.
When I started I had a problem doing this, too. The problem I had was that I was trying and trying and trying to click the ‘chain’ icon in visual editor, but it was greyed out and it didn’t seem to do anything. I did not realise that you first need to select the text that you want to use as the link anchor, before you can click the ‘chain’ icon in visual editor. If you do this, a little box will pop up asking you for the address of the link. (Hope this helps.)
