I enjoy helping people make elf names in Sindarin. The sound mutation and assimilation rules means that it's often not just a matter of sticking two words together.
Glin+Tol = Glindol
Ech+Sael = Echael
Estel+Bain = Estelvain
Gala + Gol = Galangol
If anyone wants help making names in Sindarin, feel free to send me a PM or ask on this thread.
