I know some people are unclear on the rules relating to sitting and sending resources, so here's something you might find useful.
§2 Sitting & same pc usage
§2.1 Sitting
Every player has the right to name two sitters who may play the account during an owner's absence. Sitters must play the account they are sitting to the account’s full benefit. Abuse of this function is punishable.
Permanently sitting an account for a player that is absent for more than 2 weeks is not allowed. Foreseeable periods of absence longer than two weeks must be reported to a Multihunter before the departure of the owner.
There is no compensation for damages done by a sitter. Owners of an account are fully responsible for the actions of any sitters for their account. In the event that sitters of an account do not follow these rules and the General Terms and Conditions of Travian, both the account owner and the sitter may be punished.
For restrictions on resource transfers between sitters and sittees (see §3.2.).
§3 Resource transfers
Every account has to be played to its own benefit and may not be used only to support another account. Being blackmailed into sending resources exceeding the hourly production of the account as described below is not considered a benefit to the account.
§3.1 General
In any 24 hour period, regular one-sided transfers with another player may only equal one hour of resource production, including marketplace transactions. One hour of resource production is the total of all resources produced in all villages without subtracting the upkeep for troops.
The abovementioned amount of resources must be split in cases of multiple regular one-sided transfers with specific players. The size of the affected accounts does not matter.
If your troops are reinforcing another player’s village which is under attack, you are allowed to send enough wheat to that player to feed your troops. Normally a sufficient and allowable amount of wheat is enough to keep the troops alive for another 24 hours.
§3.2 Sitting & same pc usage
You may not make one-sided transfers of resources to another player entered as ‘same pc usage’ or as a sitter.
Resources may only be traded at a ratio of 1:1 and the resource transfer has to be finished within 48 hours. An exception to this rule is the sending of crops to feed troops that are reinforcing the “same pc users” or “sitters” that get attacked. You may transfer enough wheat to feed your troops that are reinforcing such a village. These transfers should be considered rare exceptions and must stop after 3 days from the first delivery of wheat.
In the event of a one-sided transfer, you should wait 48 hours after the last one-sided transfer has been successfully delivered before connecting with each other using the sitter function or ‘same pc usage’.
Additionally, you must wait 48 hours before making one-sided transfers after canceling sitter status or ‘same pc usage’.
§3.3 Wonders of the World and Constructions Plans
The only exception to the aforementioned rule applies to builders of Wonders of the World who actually participate in the race to the level 100 Wonder of the World. Neither the builders nor the suppliers are bound by the transfer limits.
Furthermore the keepers of construction plans may be supplied with any amount of wheat from any account, even if it is connected via sitter or ‘same pc usage’ function, to keep the troops in the village with the construction plan alive.
