Since this has been brought up:
If there is a public or exclusive feature that you'll need (ORK: see here for details, Makinom: see here for details), you can also team up with others and pay for the development costs together.
Rules:
1 post in this thread with a link to your own topic on the feature
choose a representative for the group to communicate with me, things get out of hand otherwise :)
no money talk in the forum, keep that in private conversations
So, it's simple - first, create a thread with your feature proposal and ask for others to join. After that, post a small description and link here for others to find it :)
