Hi Kreerk,
These posts should give you some idea of how forums parties come together.
The primary ingredients are:
~ People who share a love of piano music (regardless of their ability to play)
~ A piano (duh), hopefully in tune and good working condition
~ Some food and drink (with participants typically contributing by bringing some food and/or drink with them)
~ A relaxed, let's have fun atmosphere.
~ We usually encourage everyone to take a turn at playing, regardless of whether they just started learning, or just released their 5th concert CD
~ Pictures, lots of pictures. If a grand piano is involved, pictures should include a group shot, with as many people under/over/around the piano as possible.
Most of the parties are very informal, although some have included guest concert artists and printed programs. I think people are more likely to relax and enjoy themselves if it's low-key.
Here are some previous parties, and suggestions:
