I'm trying to answer questions on SO because I want to improve my skills. No matter how good is my knowledge - the community will always be better than that. If I answered wrong - that's mostly because I didn't get sense of question properly (shame on me, yes)
You can always find me in PHP chat room - don't hesitate to ask, if I'm available I'll try to help.
