I suppose it depends how much free time you have but there’s a serious question as to whether both forums could be merged into one super forum and then you’ve got everyone focused on growing one community huge!
Merging forum into a big forum is only a good idea when you purchase a huge forum. You could possible merge it into a big forum. However, I would always recommend starting a small forum and then growing it into a really big community. This will eventually create a large forum when more and more members will join the forum and keep your community active. You should not think about merging your forum in case if your forum is showing the signs of growth.
