Lately I was looking for a presentation forum, finding lots of people who are interested in this field, lots of questions and relevant answers.
So I registered at presentation helper and from now on I will try to answer every day to the questions posted there by people like you.
I'm not a forum-lover, but I think it's a real help for a beginner to read different posts with presentation tips and advices, to exchange opinions with others. In addition to your home study classes you can find solutions for your problems and, why not, share with everybody the new things you acquire.
By registering you can also receive an email when somebody has replied to your message. There will be a delay before your message will be displayed, so have patience.
For example, I'm waiting now for an email from them to finish my registration. As soon as I complete the form, I will be able to post messages.
See you there... ;)
