Conversions for dummies: A new series about converting.

Ok, so I am going to do a new series about doing simple conversions, this will be done step-by-step and hopefully will help people.

A couple of days ago, I was thinking about converting. I know I am not the best converter but not everybody is and it is hard to learn some of the basic skills when you join theis obby, so I will be converting on some of the following races:

Space marines.
Orks.
Dark eldar warriors.
Tyranids
Maybe some other I am not sure.

So, tell me what you think and say if your interested.
