what does the heritage green star mean

It means that the pet has Genetic Power 1. 

I'm having some trouble copying from the FAQ, so you'll have to go there and check it out yourself, but just go to Help -> FAQ and look under Genetics and Breeding Questions, question 3. 

how do you join or get a job in the forums

I'm not sure what you mean by that?? Do you mean you yourself as a user? Or pets? I am confused.

Staff members need to apply for a position on a correct board (now locked as the positions are filled), But there is a writer application going on (see General Chat board).

Hy,

Sorry for silly question, but i cant find it. How can I send an animal for training (I have riding hall and 10 + leveled animals)

/And congrats for the new mods ^^/

I think they mean become a mod

SnKMizore: Once you have the Riding Hall, the option to train a pet will show up on the pet's profile. 

If you have Riding Hall level 1, you can only train pets UP TO level 10, however. So once a pet hits level 10, the Train button will not show up anymore. If you want to train higher levels you will need to upgrade the Riding Hall. 

Oooh, I not read it good, so its up to 10 *blushing*

Thanks for the help, now I found it! :)
