I used Joomla for over 12 mths and other web tools for several years. The level of support provided by joomavatar was professional, prompt and easy to follow.
I bought the Pro version of AvatarYouTube. You will be able to show off the videos very quckly and accurately in multiple modules. Use the freebie to try it out like me first. It saved me heap of time by investing a small amount of money. What's more it come with other excellent extensions like the Avatar Photo Galleria, very easy to use too. Absolutely no cons, just one suggestion in the Photo Galleria; make sure your picasa web photo is made public.
Well done and please keep moving forward!
