I find different forums are active in different areas of modeling. RCU has a more active forum in F3A than RCG does. RCG is MUCH more friendly to uploading photos than RCU. RCG has a VERY active DLG/HLG area. RCU does not.
I look around to find an active forum with the info I seek. With the above said I made a jump to RCG and find myself making most of my posts there.
