signing up could have still implemented with the old navigation system. for me, i find the old one better to navigate with because it was easier to find something you were looking for without browsing thru too many pages.. just hit CTRL-F and you can find it on the page..
but i guess that's where the new system shines as well, with the search engine, and the individual pages for products help to compartmentalise the deal, with individual photos and contact details so its not too confusing, and not too many of the same products circulating around cuz of bumps..
pros and cons.. i still currently prefer the old one, but i think i'll learn to get used to the new system cuz it has more features packed into it.
