It has a "forum", there are  3 mailinglist, and well maintained by Jiri Gaisler the leadear/founder of the project.
Unfortunatley Leon have comercial parts e.g the FPU and the smp variant, and some ASIC assistance stuff.

OpenRISC is a concept from the scratch with completly free ideology, Leon is a sparcv7 compliance.
What if maybe sparc (TM) will one day charge for it's IP,  who knows ? Just like MIPS do it right now.

As performance and other analysis there is a comparasion between Leon2/OpenRISC/Microblaze
