The H-C rules that we all have to agree to follow to join are listed at:

If you haven't read them recently it might be a good time to look back over the list.
In particular, considering that this is a D-I-Y forum, we will be protective of the rights of patent and copyright holders, and any infringing material will have to be deleted immediately according to Rule 5 of the Terms of Use which say:
Content that violates this agreement or is offensive, illegal, obscene, threatening, or infringes on the rights of others, including the posting of material copyrighted by someone other than the person posting the material, can be removed at HC's sole discretion and the membership of those posting said content may be terminated, again at HC's sole discretion.
There are lots of free projects for all of us to build and enjoy without getting into questionable territory.
Best regards, Jack
