Problem with log in

Hi, i have two questions

I bought easdiscuss. I would buy easyblog. The profile page is the same, or i will have two different profile page, one for easdiscuss and one for easyblog?

I have another problem, but not is a problem of your extension, but none help me.
After that i write on the form, the title of the field disappears. Maybe is a problem of css.
The link is the follow:
