Welcome Chris to the forum. Otside of Lent, Wednesday and Friday are fast days (fish allowed, no meat products or dairy).
during Lent, according to each person's own ability and with the blessing and guidance of your spiritual father (priest,priestmonk) /mother (abbess), the fast is a strict fast for 50 days. fish is not allowed, and dairy products are not either.
Children, elders, the ill who cannot keep the full fast for physical reasons are allowed lee-way in this aspect. children are also allowed at times to give up things other than foods such as videogames, candy, chocolate, less television etc.
Also, many times we forget part of our Lenten confession is compassion and service to the poor, the suffering (ie. the Beatitudes). Often, a parish will take a youth group or any group of parishioners to a mission downtown and offer their services there, or they can go on a trip to help build a house, repair a church building, cleaning, visiting old-homes etc.
There are also couple liturgical services peculiar to Eastern Orthodox Christians.
The Sunday before the First sunday of Lent, an evening service "The Vespers of Forgiveness" is done where a regular vespers occurs ,and at the end, everyone lines up in front of each other and ask each other for forgiveness for the wrong they have done to each other- it is a very moving service.
Each Sunday of Lent has a theme: Sunday of Orthodoxy---> St. Mary of Egypt sunday dedicated to the various themes of repentance.
On Wednesdays of Lent, an evening liturgy called the "Prescantified Liturgy" is done. It is half a Vespers service, half a Liturgy where communion- sanctified from a previous liturgy, is given to the people.
On Fridays of Lent, an Akathist service is prayed. Akathist means "not sitting" because long ago, people did not sit during this service. It's origin lies in history when Constantinople was being held sieged by Turks (the first time) and the people sung this poetic service in front of the icon of the Virgin Mary, called Panagia (All Holy) or Theotokos (Mother of God). Thus through the prayers of the Mother of God Mary, the City was saved from the Turks.
The service is very poetic, and often alludes to biblical prototypes of the Virgin Mary, of Christ, of salvation etc. The service rotates between the choir/chanters/the people, and the priest. There is an icon of the Theotokos sitting on an elaborate chair, with Christ sitting on her lap- rightly called "The akathist icon".
