I do have a few suggestions but want to see the thoughts of others.
"Recently Reviewed" section for the Books Section so it can be seen who has been reviewing. Also if the books on the default homepage could be arranged horizontally and then vertically obviously it is more aesthetically pleasing.
Is there also a way to incorporate the costs of texts (without having to go through manually)?
Tutoring
-Variable rates. I occasionally feel a bit generous and do tutoring for a lot cheaper for holiday cram sessions/charity fundraisers/skype etc. and having a separate ad seems to clog space up quite a bit. This can be possible done as a "from x$", though I could see this getting abused perhaps =\
-Non student reviews. I personally think there is value to a review of a tutor without them actually being a student. This could be hidden by default, but could be shown if one wanted to see these.
