I would like to see a link on my portfolio page that links to all journals submitted by the borrowers I have lent to. I don't think this is a current option? I really think the journals help complete the circle Kiva has created. The only other recommendation would be to allow lenders to a specific borrower to send comments, pictures or "best wishes". Let the borrower to see the faces of those who are helping them from the other side of the earth.
Since lenders already can make comments on the journals for borrowers they loaned to, I'm not sure what additional you are asking for in that regard (other than the idea of posting pictures--which would get back to the thread discussing animal pictures representing lenders ).
Your idea about having a portfolio option that not just links to borrowers' pages but also directly to journals on those loans would be excellent. Post that one on the suggestion section for sure.
