With reference to Derek's post above, he quoted the following:
so for the time being I will just continue to lurk in the background as I feel that there is nothing that at present I could contribute to the forum.
Please remember we are here to help - So just posting a question is still contributing! You may just ask a question that others have been wondering about, and in doing so you will help them, as well as getting an answer yourself.
We don't bite (normally!), and we have members from around the world with many skills who are only too willing to give help and advice when required.
Whilst posting on a forum for the first time can seem a little daunting, remember that we've all been at that stage at some point in the past..... Once you take the plunge, you'll quickly find that not only will you generally get an answer to your problem, but that you will also develop friendships with people you would never normally meet. Just think of it as a
big club - Come on in, the water's lovely!
