Hello, i'm here to help you

about registration:
"Tau daugiau nei 5-ki ir tave masina naujos pažintys? Tada įstok į klubą "Draugas.lt" – populiariausią internetinių pažinčių klubą Lietuvoje!<...>" - that's more or less advertising

:
"are you older than 5 and you want to make friends? join the club "draugas.lt" - the most popular internet meeting club in Lithuania, etc, etc"

"trinti" means erase (clear fields)
so you should choose "toliau". it means go further. all the fields must be filled. dont forget to enter the place you live in (Miestas - means city, but as a foreigner you will find a small list of countries and continents at the end)
as much as i understand, after registering in that place you will be sent some kind of email with instructions. or maybe not

if you did that, you have achieved much

i tried and i received a letter. there you have to activate your account (second link (the longest

in the letter) i know you will find trouble in trying to sort out some things so if there are any things, just ask. i'm always ready to help
"Klubo nario zona
Jei nori prisijungti prie klubo nario zonos, užpildyk viršuje esančius laukelius ir paspausk "Jungti"":
zone of member of the club
if you want to go to the szone of member of the club, fill all the fields above and press "Jungti" (join)
the rest is chattering

"Norejau tik palinketi geros dienos!" - i'd like to wish you good day
"Va sedziu darbe... mirineju, miego noriu. Vis dar sunku atsigauti po
lietuvisku atostogu. " - sitting in my job... dyin,g sleeping. it's too difficult to recover from lithuanian holidays.
well i wouldn't pay attention at all these chatterings but if you want, i will be able to translate
