LiveCode Forums.

I'm from Indonesia, and I want to introduce livecode in my community.
if I use the domain name livecodeindonesia.com or any domain name that uses livecode.
is this allowed?

That would be a question for the trademark holder. Historically they welcome such things as long as they present the brand in a positive light, as it sounds like you intend to do.
