I'm sure lots of is have had ideas for products, parts, sets, themes or services that we'd like LEGO to produce. What are the best ways of proposing them to TLG, and of persuading them to take on our ideas?
The options of which I am already aware:
For themes and individual sets, you can make a proposal at cuusoo.com, and if you get enough votes and TLG think your idea has sufficient commercial merit then it might be made into a set.
You could try to get with TLG and if you manage it, you might be able to influence them from within.
Is there anything else we can do?
