Getting Traffic to a Hub and Epassporte Problems

[Jonno]

Hi Everyone:
I hope you are all making a few bucks today and having some fun as well! I have been making free sites for about 6 months now and have made a few sales. As I am beginning to get more sites out there I want to build a hub and drive some traffic to it. Is it acceptable to put a link from my current free sites to my hub or is that something that link list owners do not like. What are the best traffic generators for hubs? I was thinking of having a niche specific hub as most of my sites are in the mature category does that make sense?

Also

Has anyone had problems getting signed up with epassporte? I have tried several times now and even called them from the UK (on hold for ages) and still I can't get them to charge my credit card account with a pending amount which they say they need for me to validate the card and start using the account (sounds complicated but I guess they want to prove that I'm the real owner of the card I want to use to add money to an epassporte account) I really want to get it started as I've been given an opportunity for a submit pass to a linklist and I can't send the cash without an epassporte account! Any ideas anyone |confused|

Thanks in advance for any advice it is truly appreciated
