reply link not working

After logging in to this group, the reply link does not work on either my ipad 2 running IOS 8.1.3 nor my iphone 4 running 7.1.2. Not helpful really. I have had to switch on my old laptop.Also I never know which group to post a new question in, The names like Snow Leopard dont really give me a clue, so if the key word does not find an existing topic, i just end up guessing.
