I use FL  11 only and am discovering new things every now and then about it as I am completely new to it.
Well , initially I started out with many projects, and left them unfinished, but currently I'm working more primarily on a new project and have done half of it. Well I definitely want to collaborate as as you said , to learn and develop the skills to create great music. I joined the forum primarily due to this, and the opportunity to learn lots of great stuff as well. Looking forward for a reply soon. CHEERS.
