well, just like the "newest aditions" on the main page, a "newest fixations"(or something;) is a possibility - i mean, all the problems, which were created and sent directly to the sandbox - they never get to "shine" on the first page, if they're done, after 10 new probs are updated..
("shinning" is importent, i think - it helps to set a rank, and such..)
