I've been thinking quite a bit lately about this forum and it's real need for some organization when it comes to trading pets. Having a consolidated thread will do two things -
1. Make it easier to find people interested in trading - they will all be in the same place!
2. Make it easier to find threads that are NOT about trading. ;)
That said, if you are looking to make a trade, please consider these few things as well -
Please post in the thread only once, and update your post if your needs change.
This will make it easier for people to find you and your most current offerings.
Please be realistic with trades.
I know there are several pets that are coveted by a lot of people, such as the Spectral Tiger Cub or the Ethereal Soul Trader, but realistically these pets are extremely hard to obtain and one would need something equally hard to get for a fair exchange.
Consider your realm forums!
Don't forget about your own realms! I have had the most success posting in my realm forum when I have been looking for pets. This forum has been a great boon to many I know but you may find that you have like-minded people on your server! :)
Please post your battle-tag!
Posting your battle-tag makes it easy for people to find you, easy to trade your pet, and you might even make a new friend!
If you think this is something worthwhile, consider asking for a sticky so it's easily seen. I hope to see you disguised as someone else pet battling some day! ;)
