Translation of tadellos

Mike, you are very welcome, and thanks for cheering me up. The one thing about the advertisement section on top of the main page is quite right. The difference between your dress and her dress is very difficult to detect, there is only a little change in color.
It is late here. I will summarize a few points we discussed and I am looking forward to work with you on this project, hopefully for a long time. I have seen that you have already added a few words.
How long have you been practicing Spanish using this site and in which lesson are you now? I am now at vocabulary lesson number 3. It is still hard for me, but I'm quite new here and need to get better.
