After running our own board for many years, we have decided to move on to Facebook. There are a number of reasons for this, but the main one is that keeping hackers and spammers off our board was taking time we can better use to answer your questions and prepare more English learning material.
Even if you do not have a Facebook account, you can still view the questions and answers. However if you want to ask a question you will need to have a Facebook. On the other hand, until the system was abused by spammers, users of this board used to have to sign up to use it as well.
You will still see the Facebook page embedded on the site, so once you are signed up you can use it as usual. Also, thanks to Facebook's dynamic formatting you will now also be able to use 'Ask the Prof' on your smartphone or tablet.
