I cannot select a tutor

I think the issue has been solved. Thank you.

Yes, thanks for your patience. A fix for the Exchange search was pushed. This should fix search on all the Exchange pages including the tutor search when submitting an Exchange Request. All the issues reported in this thread should now be fixed. Sorry about this again.

I imagine that there are some programming bugs related to the handling of the database.

It isn’t really strange Yutaka. I do a lot of testing using my account so sometimes I don’t correct things for a while. Recent means those are the last 3 tutors you have selected to correct your writing.

Assuming that “recent” means the last three tutors I (or, all of us?) have selected, I can name other tutors who are more recent than the ones on the list. In addition to this, the second tutor on the list of “most recent three tutors” has corrected writing only three times and has been on the list for a long time.

Sounds like a bug. I will add it to our list. Thanks for letting us know.

Thank you for your reply, Mark.
