Foals….
Can not join the game must be born.
Anyone can play foals if mare ore stallion don't want to post on
    main or joining board.
Colts are chased away from herd at three, fillies never have to leave
     unless chased out at two.
Weaned at two and it is possible for a mare to have two foal by
    her side.

Miscellaneous…
I use real life time , and no speed ageing.
Stay as active as possible it make the game a lot of fun.

Positions…
LEAD STEED-Highest position in harem and can control others in
    herd.
LEAD FEMME-Almost as high as lead steed, steed has control over 
    you. Helps steed welcome the new femmes.
GENERAL-Watches out for challenges and wars
GUARDIAN-You are asked to guard horses, usually mischievous
    foals, or others that are weaker.
WATCHER-Helps General with the attacks to the steed and makes
    sure the other femora's are not hurt.
LEGACY CARRIERS-The breeders of the harem.
PEACEKEEPERS-Not best position but most important. Brakes up
    fights that take place in harem not the challenge board. On
    fights that begin for a pointless reason.
THIN ICE-Means you are close to being exiled or are new to the
    harem.
EXILED-Banned for the harem.

Being Accepted…
Once you are in a harem you are in thin ice until the lead femme
    accepts you.

Stealing…
Only mares and foals can be snuck, Three at a time
Must have some way the mare/foal begin snuck and from what
    steed.
May be hidden in riddle or font.
If steed/mare of the mare/foal does not post within 3 days the
   mare/foal is the sneakers.

Challenging…
Stallions may challenge for: territories or mares.
Mares may challenge for rank or foals.
Mares can fight with stallions, very rarely do mares win.  This is
    done when a mare does not want to go with the stallion the
    claims or sneaks her.

Wars…
Stallions can declaim war on another herd.
The winner gets the others femmes and can either take the
    territory or leave it for the loser.
You can mock battle in your herd and this normally means war.
Allies are common in wars and mock battles between herds can happen.  Femmes can travel from on herd to other if allies.
