Welcome! There's lots of smart folks around here that are much better at writing than I. If you have questions, then ask away. I'm sure someone will be along with an answer.
Well, I like your attitude........I am not a good writer either but do write some articles on my expertise.....i suggest you to just go ahead and start writing first and yes research first on topic that you want to write.......if you do not want to use internet, you can use your local library to find some good sources..
