Watch out, long post ahead!
I´m away between June the 16th and 23rd and need replacements for all of my games. I don´t mind whether a single person takes over all of them or if there´s several players each getting one or two, but someone needs to fill my place next week.
Here we go with a hopefully complete list of the PBEMs I participate in:
Give me 18, but not on Earth

This should be the easiest, you have a total of 3 units to move and nothing else to do because it´s the classical age and I´ve been reduced to only one city by Ethiopia.
Triumvirate Uprising

This one is more complicated, it´s on an Earth-map and every player controlled three civs at the start until Germany went nuts and axerushed the rest of Europe. 
My France is long gone and China is thanks to my lack of foresight and plain incompetency on the verge of destruction, but my Persia is well on its way to become a superpower and Germany´s/Russia´s biggest rival.
We are still in the BCs.

Hub Always War

Well, it´s a Hub mapscript and everyone is at war with everyone, pretty straightforward. We are still in the BCs and exploring the map, I have so far only met three of five enemies.
After the Launch

This game should be the most demanding because the situation can change on a whim and you need to react fast. We are seven players on several islands with a Modern Start and only Space Race victory condition enabled. Everything is still open.
Earth 1000

Earth map again, this time with a start in 1000 AD. I am Elizabeth of England and currently trying to fight off the Vikings in the 11th century.

A game hosted by me, in the modern era with the next war epic mod that shipped with BtS. It is still relatively early but gpcii´s Germany has already capitulated to Tigranes´ Zulu after the latter´s blitzkrieg ironically enough. I control Catherine of Russia and my civ is in a most interesting position, namely spread out over two continents.

Yet another Earth map, this time with the Earth 2010 mod, instructions for installation in one of Tigranes´ posts on the first page of the linked thread. I am Hugo Chavez of Venezuela and trying my best to gain an edge against the other players. All player civs started out as vassal to a major power, I am so far the only one who gained independence from my former master China which places me in a unique position.

Legends of Revolution: The Final Draw
http://forums.civfanatics.com/showthread.php?t=456190
You need the Legends of Revolutions mod and a good computer, because it´s on a huge map in the Renaissance. You control Carthage, Persia and Germany. All are on different continents and Persia is a vassal of Carthage while Germany is a vassal of player-led France.
If prospective replacement players could answer me in this thread or send me a PM within the next days that´d be dandy. I just hope I didn´t forget any game.
