1) Do not enter more than once on a joint account, you may say it's a different person but I have no proof, I'd advise commenting on your main account if you have one.

2) Only enter one name, sorry 2 names just makes it more complicated for me, and I feel it's unfair for people who only pick one to have to compete.

3) I know some NTA's do it, but please don't switch the name around. 

eg.

Flickerpaw - Breezeflicker

4) Don't comment more than once please, apart from replying to your own comment which is fine.

5) Have fun!
