Wa alaikum assalaam Nur!
Welcome. Don't be shy! Its a bit daunting at first to figure out how everything works (hmm, actually, I still haven't figured out a lot of it!), but its worth the effort. And everyone has something to contribute. Each person brings a new perspective, a new flavour to whatever is being debated. Speak from your Heart, and some good will come of it, inshallah.
Smile. Be a Light to us Nur!
