Welcome! Glad you joined.

Have you considered starting your build thread? I found its a great place to document my tank's evolution for myself. I started tank first then joined, so I'm still finding myself going back collecting pictures & updating historically as well as current state. Once you create your first post in your thread and link it to your account, they will give you build badge (look left, under my ID)
