So now that 3.2 is here and there have been changes to the mounts in the game (see below), I offer the following:
If you are a Guild Member above the rank of PRIVATE, the Guild will assist you in your purchase of your first mount at level 20 by contributing up to as much as 2g. The balance must be earned by you through grinding (not begging or gifts).
DETAILS FROM THE 3.2 PATCH NOTES:
Mounts
The cast time for summoning any ground mount is now 1.5 seconds, down from 3 seconds.
Apprentice Riding (Skill 75): Can now be learned at level 20 for 4 gold. Mail will be sent to players who reach level 20 directing them to the riding trainer.
Journeyman Riding (Skill 150): Can now be learned at level 40 for 50 gold. Mail will be sent to players who reach level 40 directing them back to the riding trainer.
Expert Riding (Skill 225): Can now be learned at level 60 for 600 gold from trainers in Honor Hold or Thrallmar. Faction discounts now apply (Honor Hold for Alliance; Thrallmar for Horde). Flight speed at this skill level has been increased to 150% of run speed, up from 60%.
Artisan Riding (Skill 300): Faction discounts now apply (Honor Hold or Valiance Expedition for Alliance; Thrallmar or Warsong Offensive for Horde).
In order to further equalize the number of purchasable mounts available to each race, a new 60% speed ground mount has been added for night elves, and a new 100% speed ground mount has been added for the undead.
Flying over Dalaran and Wintergrasp is now possible so long as players keep a healthy distance above the ground.
AND:
Tome of Cold Weather Flight: New heirloom item. Players who have reached level 80 can now purchase this book for 1,000 gold from Hira Snowdawn, the Cold Weather Flying Trainer in Dalaran. Similar to other heirloom items, this item can be mailed to other characters of the same realm, account and faction. The book is consumed when read training the character in Cold Weather Flying. Requires level 68.
I hope this is helpful,
