Skinny--
Welcome aboard! I, too, am a "newbie", but have already discovered a plethora of great information. I'm sure the support and advice of members will be helpful.
How about sharing your stats with us - along with what you are trying to do to gain weight/muscle. Bottom line for weight gain, of course, is calories - but the "correct" calories. Do you have a photo you canpost?
In any case, I wish you the best for success in obtaining your goals.
