Some Questions about YT

Hello BHW members,
Got some questions that need answering if anyone can help.......

1. How many YT accounts can I attach with my adsense account? Got 2 YT acc's attached at the moment

2. Is there a limit of how many daily videos I can upload on youtube ?

3. Can I re-upload my existing videos on one of my accounts to another 2-3 accounts by just giving another description to them and changing the watermark? (don't want to get into any trouble with youtube), and if yes can u suggest me a mass watermark changer ?

2 - no
3 - yes you can if you have rights for that videos (you created them) but they will be probably ranked lower on other than first channel.

1. You can have multiple accounts attached to your Adsense account, although remember, you cannot have more than one Adsense accounts.
2 and 3 ^^^ answered already.

2. There is no limit as long as your videos don't violate the rules.
