First off to make people to want to come to your Hatching STOP posting topic after topic about it begging people to come. All this will get you is members to ignore it all together. Patience means everything to your potential group hatch partners. Also you should put a link in your signature to the Egg Hatching so people might consider yours. Another thing, try to sound professional about the Hatch Which means this:
A Name for the hatch
A set date
A set time that works with everyone who has joined up
Remember I'm not trying to be mean just trying to help.
