I don´t know how to translate the concept of online, so I´m just going to try what I think I know. Hopefully someone else will correct it/fill in the blanks.

Dün gece için kusura bakma, ......

"Online" gideceksen olursan, bana mesaj gönder, geleceðim.

tesekkur ederim this is only short

"ama daha belli deðil hangi ay gelirim"

 upside-down is alt üst etmek, ters yüz etmek is inside out...

 We would say ´turning the world upside down in English´ - is that a possible translation?

Awwww, so that´s what it is, I thought arkadaþ and olmak are considered separate. Cool, thanks.

Tamam, sana inaniyorum, ama senin msn adresinin bende olduðundan emin deðilim, bana msn adresini söylemelisin.

My attempt

Well done, say hi to him/her from me. Stop worrying it´s not like that to us He leaves us with curiosity, it doesn´t go like this.  Shall I arrange someone for you here.  He saw your photo and he liked it very much. What do you think? You come here and later we bring also your cousin?  What do you say? Have a think.

Arrange it, but at the moment there is someone( in my life), our relationship is not going good now, so it would be if I leave him ..hahah actually show also Kizun (your daughter?) to him

Mmmh, that´s getting rather confusing, don´t you think? You would replace the one infection by the other then?

My apologies for posting multiple questions today - it´s just I´m going down the sentences on this link http://www.birlikteforum.com/forum/paylasim_alani/ingilizce_en_cok_kullanilan_2600_cumle-t4592.0.html (1 page down, 36 to go) and trying to translate from English to Turkish to see if I get the same result. Every now and then there´s something that just makes me wonder.

So I have another questions, more like a request for somebody to check my train of thought here.

"Are we can be friend? Arkadaþ olalým mý?"

Obviously the English translation on the website is gramatically wrong, I´m assuming it should be "Can we be friends" - if so, wouldn´t the Turkish translation be "Arkadaþlar olabilecek miyiz?" - I´m thinking "Arkadaþlar olalým mý" is more like "Let´s be friends, shall we?" - and am I correct in thinking this should be plural (arkadaþlar instead of arkadaþ)?

Thank you.
