"The official Plone trademark policy is available here":/foundation/committees/ip/policy.
"We've aimed to create a policy that is as straightforward and non-disruptive as possible", said Trademark Committee chairman Alexander Limi.
"This means that Plone User Groups and open source products can use the name with a minimum of hassle, while still protecting the trademark and brand of Plone."
The trademark committee is looking for new members to help out with protecting Plone's brand and trademark. If you're interested in helping out, please "contact us":/foundation/committees
