I'm not quite sure I'm understanding what you're saying. I realize you're using a translator from Lithuanian to English; try wording things differently. Sometimes that helps.
If I understand the first part of your post; you're saying that you know you can log in and register, but you're asking if you'll be able to see everyone else? The answer is yes; the information is all there, it depends on how you code.
As for the second part, I don't understand, sorry. Do you mean like, how much would it cost to use those two products? Well, depending on the version you're using, it looks like it's around 100-300 euros.
Also, if you're not already using it, try using the google translate at; it's supposedly pretty good:
