Anyone is willing to teach me how to use the web 2.0 module the right way ?
To be honest my good fellow the best way is to learn for yourself through trial and error.
Check the Web 2 Submitter help tab it has the basics of what to do but that is usually just a matter of registering, confirming email then creating profile and submitting article.
There are some tips to know about using each site like which site allows what and how and you can find out much more about it here but the best thing to do is try it yourself to learn and find out for yourself.
Don't be scared to break it. In fact try to break it. Find out its limitations. Create a test profile in Sick 4, open the Web2 packet. Register and confirm emails and try to create a test blog from the successfully registered sites. If any fail somehow, look into how and why and remember for the next time you create them.
The thing is with this is that like most things worth having your success is dependent on how hard you work at it. Knowledge is power but it can only come through learning for yourself.
Wisdom is whats in the bottom of the bottle not what's written on the side.
